Computational Fluid Dynamics for Dense Gas-solid Fluidized Beds: a Multi-scale Modeling Strategy
Dense gas-particle flows are encountered in a variety of industrially important processes for large scale production of fuels, fertilizers and base chemicals. The scale-up of these processes is often problematic and is related to the intrinsic complexities of these flows which are unfortunately not yet fully understood despite significant efforts made in both academic and industrial research la...

متن کاملGas-Liquid-Solid Fluidized Bed Simulation by Computational Fluid Dynamics
Gas-liquid-solid fluidized bed technique has emerged recently as one of the most promising one for three phase operations involved in chemical, biochemical, petrochemical, pharmaceutical processing industries. Out of the fundamental characteristics of a three-phase fluidized bed, the gas hold up and liquid hold up behaviours have been studied extensively. Considering the various researchers’ fi...
متن کاملHybrid Two-Fluid DEM Simulation of Gas-Solid Fluidized Beds
Simulations of gas-solid fluidized beds have been performed using a hybrid simulation method, which couples the discrete element method (DEM) for particle dynamics with the averaged two-fluid (TF) continuum equations for the gas phase. The coupling between the two phases is modeled using an interphase momentum transfer term. The results of the hybrid TF-DEM simulations are compared to experimen...
متن کاملHeat Transfer Mechanisms in a Gas – Liquid-Solid Fluidized Beds
Three-Phase Fluidized Beds have found an important place in processing technology as Reactors. Gas-Liquid-Solid fluidization is considered in the present paper as operating bed of fluidized solid particles simultaneously with co-current upward flow of a continuous liquid phase and a gaseous phase dispersed in the form of bubbles. In the present study, the experimental work of the author on heat...
