Since the Taylor microscale Reynolds number R-lambda is approximately constant (similar or equal to450) along the jet axis, the structure functions and spectra also collapse approximately when the normalization uses either the Kolmogorov or integral length scales. Over the dissipative range, the best collapse occurs when Kolmogorov variables are used. The use of and the integral length scale L provides the best collapse at large separations.

The similarity, which scales on the Taylor microscale λ and q2¯, is then used to determine s-b-s energy budgets from the data of Antonia, Zhou, and Romano [“Small-scale turbulence characteristics of two-dimensional bluff body wakes,” J. Fluid Mech.459, 67–92 (2002)] for 5 different two-dimensional wake generators. In each case, the budget is reasonably well closed, using the locally isotropic value of the mean energy dissipation rate, except near separations comparable to the wavelength of the coherent motion (CM). The influence of the initial conditions is first felt at a separation Lc¯ identified with the cross-over between the energy transfer and large scale terms of the s-b-s budget. When normalized by q2¯ and Lc , the mean energy dissipation rate is found to be independent of the Taylor microscale Reynolds number. The CM enhances the maximum value of the energy transfer, the latter exceeding that predicted from models of decaying homogeneous isotropic turbulence.]]> Wed 11 Apr 2018 15:47:49 AEST ]]> A dynamic Monte Carlo study of anomalous current voltage behaviour in organic solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17001 Wed 11 Apr 2018 15:46:34 AEST ]]> Atomic force microscopy with a 12-electrode piezoelectric tube scanner https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:11496 Wed 11 Apr 2018 15:42:40 AEST ]]> Surfactant free P3HT / PCBM nanoparticles for organic phoyovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17020 Wed 11 Apr 2018 15:36:03 AEST ]]> A novel self-sensing technique for tapping-mode atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15286 Wed 11 Apr 2018 15:26:57 AEST ]]> MaxEnt alternatives to pearson family distributions https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15284 Wed 11 Apr 2018 15:01:12 AEST ]]> The lattice Boltzmann method and the problem of turbulence https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28332 Wed 11 Apr 2018 14:39:34 AEST ]]> Erratum: investigation of the photochemistry of the poly {p-phenylenevinylene} precursor system: implications for nanolithography [J.

The ratio (5/3 + m u )/m θ is approximately 2, in close conformity with the proposal of Danaila and Antonia [“Spectrum of a passive scalar in moderate Reynolds number homogeneous isotropic turbulence,” Phys. Fluids21, 111702 (2009)].]]> Wed 11 Apr 2018 11:48:55 AEST ]]> Scaling of normalized mean energy and scalar dissipation rates in a turbulent channel flow https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12259 ε and Cεθ are examined using direct numerical simulation (DNS) data obtained in a fully developed turbulent channel flow with a passive scalar (Pr=0.71) at several values of the Kármán (Reynolds) number h+. It is shown that Cε and Cεθ are approximately equal in the near-equilibrium region (viz., y+ = 100 to y/h = 0.7) where the production and dissipation rates of either the turbulent kinetic energy or scalar variance are approximately equal and the magnitudes of the diffusion terms are negligibly small. The magnitudes of Cε and Cεθ are about 2 and 1 in the logarithmic and outer regions, respectively, when h+ is sufficiently large. The former value is about the same for the channel, pipe, and turbulent boundary layer, reflecting the similarity between the mean velocity and temperature distributions among these three canonical flows. The latter value is, on the other hand, about twice as large as in homogeneous isotropic turbulence due to the existence of the large-scale u structures in the channel. The behaviour of Cε and Cεθ impacts on turbulence modeling. In particular, the similarity between Cε and Cεθ leads to a simple relation for the scalar variance to turbulent kinetic energy time-scale ratio, an important ingredient in the eddy diffusivity model. This similarity also yields a relation between the Taylor and Corrsin microscales and analogous relations, in terms of h+, for the Taylor microscale Reynolds number and Corrsin microscale Peclet number. This dependence is reasonably well supported by both the DNS data at small to moderate h+ and the experimental data of Comte-Bellot [Ph. D. thesis (University of Grenoble, 1963)] at larger h+. It does not however apply to a turbulent boundary layer where the mean energy dissipation rate, normalized on either wall or outer variables, is about 30% larger than for the channel flow. © American Institute of Physics]]> Wed 11 Apr 2018 11:45:27 AEST ]]> A megahertz bandwidth dual amplifier for driving piezoelectric actuators and other highly capacitive loads https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7752 Wed 11 Apr 2018 11:13:46 AEST ]]> Continuous MaxEnt distributions in Mathematica: a 'parameter-free' approach https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9105 Wed 11 Apr 2018 10:53:04 AEST ]]> An overview of the effect of large-scale inhomogeneities on small-scale turbulence https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3136 Wed 11 Apr 2018 10:50:12 AEST ]]> Enhanced regeneration of degraded polymer solar cells by thermal annealing https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17005 61-butyric acid methyl ester (PCBM) and P3HT:indene-C60 bisadduct (ICBA) polymer solar cells, with Ca/Al and Ca/Ag cathodes and indium tin oxide/poly(ethylene-dioxythiophene):polystyrene sulfonate anode have been investigated. Degradation occurs via a combination of three primary pathways: (1) cathodic oxidation, (2) active layer phase segregation, and (3) anodic diffusion. Fully degraded devices were subjected to thermal annealing under inert atmosphere. Degraded solar cells possessing Ca/Ag electrodes were observed to regenerate their performance, whereas solar cells having Ca/Al electrodes exhibited no significant regeneration of device characteristics after thermal annealing. Moreover, the solar cells with a P3HT:ICBA active layer exhibited enhanced regeneration compared to P3HT:PCBM active layer devices as a result of reduced changes to the active layer morphology. Devices combining a Ca/Ag cathode and P3HT:ICBA active layer demonstrated ∼50% performance restoration over several degradation/regeneration cycles.]]> Wed 11 Apr 2018 10:49:00 AEST ]]> On the Batchelor constant in decaying isotropic turbulence https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3134 Wed 11 Apr 2018 10:22:48 AEST ]]> Note: A method for estimating the resolution of nanopositioning systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15092 Wed 11 Apr 2018 10:17:19 AEST ]]> Resonant control of an atomic force microscope micro-cantilever for active Q control https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15213 Wed 11 Apr 2018 10:10:05 AEST ]]> Field emission from single-, double-, and multi-walled carbon nanotubes chemically attached to silicon https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15214 Wed 11 Apr 2018 10:05:55 AEST ]]> A first-principles density functional study of chlorophenol adsorption on Cu₂O(110):CuO https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7987 Wed 11 Apr 2018 10:05:26 AEST ]]> Simulation of dynamics-coupling in piezoelectric tube scanners by reduced order finite element analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:4350 Wed 11 Apr 2018 10:03:58 AEST ]]> Energy-filtered phase retrieval using the transport of intensity equation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:11880 Wed 11 Apr 2018 09:59:10 AEST ]]> Properties of d- and k-type roughness in a turbulent channel flow https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3129 Wed 11 Apr 2018 09:58:36 AEST ]]> Nanoscale band gap spectroscopy on ZnO and GaN-based compounds with a monochromated electron microscope https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7983 Wed 11 Apr 2018 09:44:54 AEST ]]> Electronic effects induced by single hydrogen atoms on the Ge(001) surface https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:4355 Wed 11 Apr 2018 09:42:12 AEST ]]> Comparing model parameters of bulk heterojunction and nanoparticulate photovoltaic cells using a two-diode model https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17018 Wed 11 Apr 2018 09:33:25 AEST ]]> Description, recognition and analysis of biological images https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:10052 Wed 11 Apr 2018 09:22:34 AEST ]]> Epid dosimetry https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17229 Wed 11 Apr 2018 09:16:39 AEST ]]> Compressible gas-solid mixture conservation laws simulations https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15285 Wed 11 Apr 2018 09:13:28 AEST ]]> A grounded-load charge amplifier for reducing hysteresis in piezoelectric tube scanners https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:158 Tue 27 Aug 2024 16:49:38 AEST ]]> On the normalized turbulent energy dissipation rate https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16 50) although, for a given flow and initial conditions, it is independent of R-lambda when the latter is sufficiently large.

Second, the relevance of different sets of similarity variables for normalizing the energy spectra and structure functions is explored. In particular, a new set of shear similarity variables, emphasizing the range of scales influenced by the mean velocity and temperature gradient, is derived and tested. Since the Reynolds number based on the Taylor microscale increases with respect to the streamwise distance, complete self-preservation cannot be satisfied; instead, the range of scales over which spectra and structure functions comply with self-preservation depends on the particular choice of similarity variables. A similarity analysis of the two-point transport equation, which features the large scale production term, is performed and confirms this. Log-similarity, which implicitly accounts for the variation of the Reynolds number, is also proposed and appears to provide a reasonable approximation to self-preservation, at least for u and θ.]]> Fri 16 Aug 2024 14:40:13 AEST ]]>
