Assuming a total ventilation air flow rate of 300 m³/s, fifteen 20 m³/s modules would be required, producing a total of up to 11,700 kWR of cooling. The net power produced was zero between reactor temperatures of 500 and 700 °C at the investigated steam pressures (2.0–7.0 bar). Excess net power was produced at reactor temperatures greater than 700 °C due to the restriction of the inlet VAM temperature to 600 °C (to prevent auto-ignition of the methane upstream of the reactor). At low reactor temperatures the steam flow rate decreased with both reactor temperature and steam pressure but remained constant at reactor temperatures of 750 and 800 °C. The methane abatement plant would be able to operate without an external power supply through the utilisation of the process heat. The plant would produce adequate cooling for a typical gassy underground coal mine in Australia. Such mines are located in the Bowen Basin of Queensland; a region characterised by high virgin rock temperatures with cooling requirements of up to 7000 kWR.]]> Thu 11 May 2023 13:15:08 AEST ]]> Three dimensional modeling of an isothermal PROX microreactor https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8892 Sat 24 Mar 2018 08:40:45 AEDT ]]> A study of the influence of wall R-value on the thermal characteristics of Australian housing https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8835 Sat 24 Mar 2018 08:38:22 AEDT ]]> The influence of wall properties on the thermal performance of Australian housing https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9126 Sat 24 Mar 2018 08:38:17 AEDT ]]> High-pressure gasification reactivity of biomass chars produced at different temperatures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8024 Sat 24 Mar 2018 08:36:49 AEDT ]]> Influence of pyrolysis conditions on the structure and gasification reactivity of biomass chars https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1930 Sat 24 Mar 2018 08:33:20 AEDT ]]> A comparative study between a fluidized-bed and a fixed-bed water perm-selective membrane reactor with in situ H<sub>₂</sub>O removal for Fischer-Tropsch synthesis of GTL technology https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:15272 ₂ yield in CFMR in comparison with FMFMR owing to applying a fluidized-bed concept instead of a fixed-bed concept in which more effective temperature management is achieved.

The particles motion was modelled by discrete element model (DEM) whilst the gas flow field was solved using the computational fluid dynamics (CFD) method. A two-way coupling algorithm was applied to take into account gas-particle interactions. The influence of boundary conditions and the sensitivity of domain size were tested. The model was then used to examine effects of the superficial gas velocity on the mixing/segregation behaviour of particles in terms of mixing index. The results showed that small domain sizes (i.e. with the width of the 2D domain size being a quarter of the fluidized bed diameter) can be used effectively in combination with the periodic boundary conditions to capture the overall mixing and segregation behaviour of binary system of particles in a large scale fluidized bed system. Also it was demonstrated that the domain size has minor influence on simulation results when using periodic boundary conditions. Moreover increasing the size of polyethylene particles in the binary mixture was found to decrease the mixing index resulting in poor mixing. Finally simulation results were compared with the experimental data under bubbling fluidized bed conditions. A reasonable agreement between the experimental data and the model predictions of the mixing index was obtained.]]> Sat 24 Mar 2018 07:51:27 AEDT ]]> A new stable finite volume method for predicting thermal performance of a whole building https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4943 Sat 24 Mar 2018 07:48:04 AEDT ]]> Modified exponential schemes for convection-diffusion problems https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4970 Sat 24 Mar 2018 07:46:56 AEDT ]]> Factors influencing the ignition of flames from air-fired swirl pf burners retrofitted to oxy-fuel https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5321 Sat 24 Mar 2018 07:45:57 AEDT ]]> Application of neuro-fuzzy model to evaluate the thermal performance of typical Australian residential masonry buildings: II https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6263 Sat 24 Mar 2018 07:44:15 AEDT ]]> Assessment of thermal performance of two masonry walling designs for housing using a combined theoretical and experimental approach https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6202 Sat 24 Mar 2018 07:43:48 AEDT ]]> A 3D numerical study of detonation wave propagation in various angled bending tubes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26524 Sat 24 Mar 2018 07:23:29 AEDT ]]> A 3D numerical study on the effects of obstacles on flame propagation in a cylindrical explosion vessel connected to a vented tube https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26525 Sat 24 Mar 2018 07:23:29 AEDT ]]> Thermal study of decomposition of selected biomass samples https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3468 Sat 24 Mar 2018 07:20:34 AEDT ]]> Hydrogen looping approach in optimized methanol thermally coupled membrane reactor https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23737 −1) is required in this configuration.
