In this work the authors report on a CFD simulation of a pipe flow model. Fluid mechanics are here combined with heat transfer phenomena. To create a mathematical model of a pulsed hot wire system i.e., the thermo-fluidic impulse response of a pulsed hot wire, a simulation model is going ... Per saperne di più
Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper ... Per saperne di più
The current work is aimed to simulate the production of high quality fatty acid methyl ester (biodiesel) production from palm oil in a micro porous ceramic membrane reactor. The TiO2/Al2O3 ceramic membrane was used as the separator and catalytic bed. It was packed with potassium ... Per saperne di più
