Pure mineral samples were sieved to the 63 - 90 mum size fraction and tested using our custom-made electrostatic agglomeration rig. A dry particle bed of 2 - 5 mg was formed on a glass slide on a metal charging plate and the bed raised toward a pendent, earthed water droplet at 50 µm·s^-1. The particles transfer, or jump, to the droplet as the electric field between the bed and droplet changes during approach, resulting in a net force on the particles. At applied voltages ranging from 1.5 - 3.0 kV the separation between the bed and particles when the particles were first observed to transfer was monitored. For each mineral the separation increased with applied voltage due to increased electric field strength. Pure goethite transferred most readily at all voltages as the drop-bed separation distance when the first particle was observed to jump was the greatest, whereas haematite and silica behaved similarly. High cohesion between goethite and haematite particles in mixed particle beds of both minerals resulted in particles transferring to the drop at separations between those observed for beds of the pure minerals. Careful determination of mineral composition of the dry bed and the transferred particle sample will indicate whether this approach may have potential application as a "rougher"-type step in the separation of goethite from haematite.]]> Tue 20 Sep 2022 08:42:32 AEST ]]> Investigation of a Novel Emulsion Binder for Recovering Ultrafine Hydrophobic Particles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44614 Tue 18 Oct 2022 08:44:24 AEDT ]]> Modelling the tsunami threat to Sydney Harbour (Port Jackson) with comparisons to historical events https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33791 W from the Puysegur and New Hebrides trenches as well as representations of historical events from Chile in 1960 and Japan in 2011. TsuDAT wave trains include those modelled from the Tonga, Chile, New Hebrides and Puysegur trenches and have ARI ranging from 200 to 36500. Using the hydrodynamic model ANUGA, results show that the events modelled have the potential to cause terrestrial inundation, high current speeds, hazardous depths and rapid changes in water level. Maximum current speeds vary in both range and magnitude according to location. Tsunami wave trains sourced from lower magnitude events and those with lower ARI result in lower maximum current speeds. As T2 source event increases in magnitude and TsuDAT ARI increases, maximum current speeds become higher. For T2 wave trains of ≤8.5M_W, although current speeds may be a hazard, terrestrial inundation is minimal. As the T2 wave trains increase in source magnitude, inundation becomes apparent at Manly and in the low-lying embayments on the south side of the harbour. For the most impactful wave trains, TsuDAT wave trains which include ARI from 5000-36500, inundation is widespread and in some locations occurs above 10m elevation.]]> Tue 15 Jan 2019 12:58:00 AEDT ]]> A Stochastic Framework for Predicting Transfer Chute Blockages Based on Materials Properties https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43071 Tue 13 Sep 2022 09:45:30 AEST ]]> Wave Runup and Setup on Natural Beaches in NSW https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54259 Tue 13 Feb 2024 13:33:07 AEDT ]]> The contribution of submarine landslides to the 2016 Kaikōura tsunami https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54230 Tue 13 Feb 2024 12:18:23 AEDT ]]> The prediction of bulk material adhesion using a modified Instantaneous Yield Locus (IYL) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37542 Tue 09 Feb 2021 10:50:26 AEDT ]]> Calibration procedure of Discrete Element Method (DEM) parameters for cohesive bulk materials https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37541 Tue 09 Feb 2021 10:43:19 AEDT ]]> Water level trends in NSW coastal lakes by use of exceedance probability analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45908
This paper investigates the rates of SLR in two coastal lakes in NSW - Lake Macquarie and Lake Illawarra, the latter of which had entrance training completed in 2008. Tide gauge data is used to assess trends in exceedance probability values of low, median and high water levels represented by 95%, 50% and 5% exceedance probability respectively within coastal lakes and ocean conditions at Patonga for proxy. In addition, the relationship between coastal lake water levels and ENSO are investigated. Within Lake Macquarie both median and high water levels have shown significant increases, however, high water levels have shown the greatest increases most noticeable in the entrance channel at Swansea. This indicates increases in water level range and increased exposure to ocean tides and conditions. ENSO, represented by the Southern Oscillation Index (SOI) was shown to be responsible for up to 6% of water level variability within Lake Macquarie, highlighting the need to incorporate large-scale oscillations when assessing potential inundation hazards in these systems.

Lake Illawarra exhibited a response to entrance training through a significant increase in high water levels within the lake. Since entrance training, high water levels have increased at rate of up to 9.3 mm per year which is over three times the global SLR estimate. The minimal association between water level variation within Lake Illawarra and the SOI, together with increased water level ranges due to rapid annual increases in high water levels indicated a dynamic response to entrance training. This dynamic nature highlights the necessity of regular monitoring of SLR within the lake and robust inundation hazard modelling.]]> Tue 08 Nov 2022 09:25:08 AEDT ]]> Rising tides: Tidal inundation in South east Australian estuaries https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45907 Tue 08 Nov 2022 09:18:06 AEDT ]]> Covalent surface modification of biomimetic silica particles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22574 Tue 08 May 2018 18:11:53 AEST ]]> Evaluating tsunami warnings using inundation model results https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39957 th percentile of the maximum wave amplitudes (over time) of the relevant T2 scenario within each coastal zone (P95). Threshold values for P95 have previously been derived through analysis of observed impacts for recent events. Given that historical records are available for only a short time period and no observations exist for which a Land Threat would have been issued for Australia, it has been difficult to determine the appropriate threshold for a Land Threat. Several recent tsunami hazard assessment studies have used inundation models nested within T2 scenarios. These modelling results are used to evaluate the threshold values for JATWC tsunami warnings and provide guidance on a possible further warning tier - Major Land Threat. The optimum Land Threat threshold for P95 is found to be 48.5cm, however, it is not recommended that any changes are made from the existing operational threshold of 55cm. The optimum threshold for P95 a Major Land Threat is found to be 150.5 cm.]]> Tue 04 Oct 2022 15:13:11 AEDT ]]> Exploiting particle methods to investigate the structural integrity of maritime platforms https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43859 Tue 04 Oct 2022 12:07:29 AEDT ]]> Tidal dynamics and oscillations within coastal lakes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34010 Thu 31 Jan 2019 10:14:09 AEDT ]]> Desliming ultra-fine iron ore in the REFLUX™ graviton https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37539 Thu 25 Feb 2021 21:18:51 AEDT ]]> Analysis of silo asymmetry normal pressures due to eccentric discharge using DEM simulation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27049 Thu 25 Feb 2021 18:37:52 AEDT ]]> Ship motion induced moisture migration modelling of an unsaturated coal cargo https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28363 Thu 25 Feb 2021 18:30:52 AEDT ]]> Comparative investigation on modelling wet and sticky material behaviours with a simplified JKR cohesion model and liquid bridging cohesion model in DEM https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29842 Thu 25 Feb 2021 18:23:52 AEDT ]]> A data-driven approach to the fraction of broken waves https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39866 Q_b) is a key parameter for parametric surf zone models. It is via this variable that these models control the energy dissipation in the surf zone. Historically, Q_b has been obtained using probability distribution functions (PDFs) of the wave height (p(H)). This paper describes an alternative, data-driven approach to obtaining the fraction of broken waves that is a significant improvement over the more traditional approaches. This new model is based on an ensemble of regression trees in which Q_b is learnt directly from an extensive field dataset. The ensemble uses three input parameters that are often available to coastal engineers: offshore significant wave height (𝐻_𝑚0∞), offshore peak wave period (𝑇_𝑚01∞), and time-averaged relative water depths relative to the mean sea level (h/𝐻_𝑚0∞), and predicts Q_b at an averaged given relative water depth. The results indicate that the model can predict the depth-dependent variability of Q_b with a high degree of accuracy (averaged r² ≥ 0.95, averaged root mean square error ≤ 0.05, averaged mean absolute error ≤ 0.04) in virtually no computational time. When compared to three widely used Q_b models that are derived from PDFs of the wave heights, the model developed here showed significant improvement with reductions in the errors (average error reduction of 25%) and significant improvement for r²-scores (average increase ≥ 30%). Although complex, the method developed here could be advantageous over the more traditional approach because of its high degree of precision and accuracy and because it does not depend on prior knowledge of p(H). In summary, the present model could be used as a replacement for the formulation of Q_b in parametric wave models, which should result in better overall predictions, and thus, in better coastal management tools.]]> Thu 21 Jul 2022 09:34:35 AEST ]]> A comparison of tsunami inundation model results for drowned river valleys using either static or dynamic tidal inputs https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39858 Thu 21 Jul 2022 09:34:26 AEST ]]> Extremes in rainfall and runoff in the Monsoonal North West of Australia derived from paleoclimate archives https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29267 Thu 20 Oct 2022 13:23:41 AEDT ]]> Establishing the hierarchy of influence of drivers of seasonal rainfall variability in South Australia to inform seasonal rainfall forecasting https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26489 Thu 20 Oct 2022 09:48:01 AEDT ]]> The potential for tree ring hydrologic reconstructions in Australia - what does the future hold? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35382 Thu 20 Oct 2022 09:47:45 AEDT ]]> Droughts and pluvials in the Murray-Darling Basin over the past two and a half millennia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26494 Thu 20 Oct 2022 09:39:09 AEDT ]]> Assessing techniques for reconstructing paleoclimate rainfall in the Murray-Darling Basin, Australia, in the absence of in-situ archives https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26493 Thu 20 Oct 2022 09:38:14 AEDT ]]> A fractographic and tribological approach to understanding coke strength https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24267 Thu 17 Nov 2016 14:38:51 AEDT ]]> On the rheology of dispersions of temperature-responsive polymer-particle hybrids https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44431 Thu 13 Oct 2022 09:58:34 AEDT ]]> Freezing temperature of water drops https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44433 Thu 13 Jul 2023 14:46:58 AEST ]]> Australian Coal Mining industry (1797- 1820s): beginnings, history and the vanished industrial heritage of early Newcastle https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26030 Thu 12 Apr 2018 14:04:58 AEST ]]> Weber Number Effect on Molten Droplet Impingement on a Flat Substrate https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42714 Thu 01 Sep 2022 11:33:33 AEST ]]> The variability of the quality of fly ash available for disposal in a power station high concentration slurry pumping plant https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30135 Sat 24 Mar 2018 07:39:12 AEDT ]]> Investigations and modeling of the layer fraction in horizontal slug flow pneumatic conveying https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29424 Sat 24 Mar 2018 07:36:13 AEDT ]]> The evolution of slug porosity characteristics in horizontal slug flow pneumatic conveying https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29425 Sat 24 Mar 2018 07:36:13 AEDT ]]> Transient climate response in the DICE integrated assessment model of climate-economy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29177 2). Central to any IAM is a climate model capturing the dynamic response of global surface temperature to changes in net downward radiative forcing due to the atmospheric accumulation of heat-trapping greenhouse gases. The transient climate response (TCR), defined as the temperature change at the time of CO₂ doubling under a scenario in which CO₂ concentrations increase by 1% yr^-1, plays a central role in quantifying the economic impacts of climate change on policy-relevant timescales. In this paper, we propose an optimization-based methodology for computing the parameters of a climate model in such a way that the resulting model exhibits a specified TCR. The methodology developed in this paper targets the climate model parameterization employed in DICE (Dynamic Integrated model of Climate and the Economy), a widely studied IAM for which TCR is only indirectly specified. Results reported herein enable policymakers using DICE to compute optimal CO₂ emissions pathways which directly reflect the TCR of state-of-the-art climate models documented in the most recent(Fifth) Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC).]]> Sat 24 Mar 2018 07:35:44 AEDT ]]> How and why are floods changing in Australia? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26492 Sat 24 Mar 2018 07:35:37 AEDT ]]> Modelling daily rainfall along the east coast of Australia using a compound distribution Markov Chain model https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26495 Sat 24 Mar 2018 07:35:36 AEDT ]]> Exploiting climate state information in urban water supply planning and operation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26487 Sat 24 Mar 2018 07:35:35 AEDT ]]> Spatial analysis of Australian seasonal rainfall anomalies and their relation to east coast lows on the Eastern-Seaboard https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26488 Sat 24 Mar 2018 07:35:35 AEDT ]]> Revision of AS4156.6 - coal preparation - part 6: determination of dust/moisture relationship for coal https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30148 Sat 24 Mar 2018 07:34:31 AEDT ]]> Experimental and numerical investigation into silo quaking https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29289 Sat 24 Mar 2018 07:32:53 AEDT ]]> Electrostatic aggregation of mineral particles around a water droplet https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29275 Sat 24 Mar 2018 07:32:50 AEDT ]]> A multiproxy 1000-year hydroclimate reconstruction for eastern Australia and implications for water resource management https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29757 Sat 24 Mar 2018 07:32:17 AEDT ]]> Major floods - random or irregular? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29754 Sat 24 Mar 2018 07:32:17 AEDT ]]> The traction of point-contact drives utilised in pouch conveying systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30092 Sat 24 Mar 2018 07:31:13 AEDT ]]> Measurement of fluctuating velocities and dispersion behaviour of particles in a solid-liquid fluidised bed https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26045 Sat 24 Mar 2018 07:26:27 AEDT ]]> Pressure drop and voidage measurement in solid-liquid fluidized bed: experimental, mathematical and computational study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26046 Sat 24 Mar 2018 07:26:26 AEDT ]]> Expansion behavior of binary solid-liquid fluidised bed with different solid mass ratio https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25529 -3 were fluidised in water.

As the area of liquid interface exposed is directly related to the evaporation rate, a discretised pixel map of the surface of the liquid was created. The decrease in the level of the liquid due to evaporation reduced the space available for the particles to move with the consequence that the aggregation rate increased. In addition, the decrease in the level of the liquid forced the particles to settle. When the height of the liquid was comparable to the height of the sediment, the evaporation process slowed down due to the reduction in the surface area available for evaporation.

The fluidized sand medium, subjected to vibration, expanded towards the upper screen, permeating strongly through the large Sink-Hole, and to a lesser extent through the finer apertures. In fact, the excess sand on the upper screen then returned back to the lower fluidized bed via the fine screen apertures. The upward movement of the suspension through the Sink-Hole produced a strong density based separation of the larger tracer particles. It was possible to achieve sharp separation at different separation densities under batch conditions. This paper reports the effect of varying air rate and bed mass on the separation performance. Density cut points in the range 2500 to 3200 kg/m³ were obtained, which are significantly higher than the density of fluidised media, at separation efficiency (Ep) values of around 0.15.]]> Fri 26 Feb 2021 09:40:51 AEDT ]]> Monitoring irrigation volumes using climate data and remote sensing observations https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35122 Fri 21 Jun 2019 10:54:17 AEST ]]> Multi-variable hydrological simulation in a semi-arid catchment towards effective water resources management https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35114 0.5), the SWAT calibrated only to the streamflow did not provide reasonable soil moisture estimation at the HRU scale. Furthermore, the two calibrations showed significantly different catchment water budget estimation over long run. The SWAT calibrated against streamflow showed significantly less soil moisture store (21%) while much higher estimation for evapotranspiration (61%), while the multi-variable calibration model showed higher soil moisture stored (34%) but less evapotranspiration (47%). This different partitioning of the precipitation between soil moisture and streamflow was persistent throughout the seasons and this, in turn, affected the streamflow generation processes. This difference in the model prediction clearly has important implication for water management for the region, highlighting the importance of considering multiple hydrologic variables to improve model parameterization.]]> Fri 21 Jun 2019 10:25:58 AEST ]]> Balancing competing objectives in coastal entrance management https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32753 Fri 20 Jul 2018 15:38:15 AEST ]]> Bubble oscillation and motion in a filamentary streamer cavitation structure induced by power ultrasound https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48426 Fri 14 Jun 2024 08:55:28 AEST ]]> Experimental study of bubble dynamics in a droplet driven by an ultrasound standing wave https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43917 Fri 14 Jun 2024 08:19:50 AEST ]]> Towards sub-catchment scale soil moisture prediction: a combined remote sensing and land surface modelling approach https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35054 Fri 14 Jun 2019 14:37:38 AEST ]]> Identifying the existence of any periodicity in flooding https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35319 Fri 12 Jul 2019 16:25:19 AEST ]]> Revised coal dustiness test method AS4156.6 - part 2: preparation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45736 Fri 04 Nov 2022 09:59:13 AEDT ]]> Interstitial particle liquid bridge formation and its breakage by vibration https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45722 Fri 04 Nov 2022 09:45:11 AEDT ]]> Some theoretical consideration of stress states at the hopper feeder interface https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45723 Fri 04 Nov 2022 09:45:08 AEDT ]]> Investigation of impingement angle influence on impact wear of different chute liners by employing a novel impact wear tester https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45720 Fri 04 Nov 2022 09:38:03 AEDT ]]> Formation of water droplets by co-injection in an immiscible liquid at low temperatures https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49839 Fri 02 Jun 2023 17:06:58 AEST ]]> Quantifying the fraction of broken waves on a high energy east coast Australian beach https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34017 b) is a fundamental variable in parametric wave height transformation models. It plays a key role in quantifying how much energy dissipation occurs due to wave breaking. Several authors have used different parameterisations to account for Q_b; however, to the authors' knowledge, very few studies have experimentally obtained a value for the fraction of broken waves across the surf zone using field data. This paper addresses this issue by describing a methodology to quantify Q_b using a combination measured pressure transducer data and remotely sensed data collected at the northern end of Seven Mile Beach, Gerroa, NSW. Pixel intensity timeseries were extracted from a timestack at the exact locations where the pressure transducers were deployed. These timeseries are compared to individual waves identified in the pressure record and the waves are classified as broken if a strong pixel peak matches a wave crest. When compared to visually identified waves, the broken wave classification algorithm was found to be correct 94.25% of the time. Results indicate that Q_b is inversely proportional to water depth but highly variable at similar mean water depths. The variability in Q_b showed a degree of correlation with the variation in the ratio between short (seaswell) and long (infragravity) wave energy in the inner surf zone. Probability density functions for all waves and broken waves are calculated and results indicate that wave heights in the surf zone (broken and unbroken) are not Rayleigh distributed. In fact, wave height distributions were statistically different to the Rayleigh distribution for all cases analysed, whereas they are fully described by a normal distribution in 87.65% of the cases for broken waves and in 80.25% of the cases for all waves.]]> Fri 01 Feb 2019 10:37:09 AEDT ]]>
