Additionally, results published in the literature encompassing bubbles with lower values of Eo numbers were also considered, such that the overall dependencies of bubble shape, wake characteristics, and drag coefficient over a large range of Eo and Re values can be identified. While it was found that the deformation of the bubbles as predicted through the numerical study can generally replicate experimental observations presented, several limitations were identified, such as in the representation of skirt formation behind a skirted bubble and the formation of satellite bubbles behind a bubble rising at high Reynolds numbers. The dependency of the bubble aspect ratio on the Weber and Morton numbers was confirmed for cases of spherical and ellipsoidal bubbles; whilst for spherical cap and skirted bubbles the aspect ratio was found to depend largely on the Reynolds and Capillary numbers, respectively. Finally, the expansion and formation of closed/open laminar wakes behind the rising bubble were analysed and was found to correlate well with the bubble Re and Eo numbers.]]> Thu 21 Oct 2021 12:53:06 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47435 Thu 19 Jan 2023 16:47:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43284 Thu 15 Sep 2022 12:30:31 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19002 Sat 24 Mar 2018 08:05:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20753 Sat 24 Mar 2018 08:00:25 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17741 Sat 24 Mar 2018 07:57:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17714 Sat 24 Mar 2018 07:57:25 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18347 137Cs radioactive source. Measurements were taken at different axial levels, for different chordal positions. An Eulerian–Eulerian approach was used to simulate the gas–solid flow in the stripper column. The CFD simulations predicted asymmetric solid holdup profiles emphasizing the importance of 3D simulations. The CFD model predictions matched well with the solid holdup data from experiments. The CFD model also clearly predicted the recirculation and dead zones as noticed in the experimental analysis. Local defluidization zones were also noticed near the donut baffle wall regions. The particle axial velocity was low near the baffle walls, indicating that the particles slide down on the baffle walls. The radial and axial variations of solid holdup are discussed in this work, giving new knowledge in the complex countercurrent operation. This work is first of its kind to report detailed 3D study on the hydrodynamics of stripper operation both in cold flow and in the CFD model.]]> Sat 24 Mar 2018 07:52:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18569 Sat 24 Mar 2018 07:50:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26856 Sat 24 Mar 2018 07:41:46 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26549 Sat 24 Mar 2018 07:26:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25003 Sat 24 Mar 2018 07:09:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39744 Fri 17 Jun 2022 18:27:07 AEST ]]>
