Entitled: Computational and experimental study of hydrodynamic and heat Transfer for the binary mix of solid particles in a three-phase fluid bed reactor
The hydrodynamic characteristics and heat behavior were investigated in a co-current gas-liquid-solid fluidized bed containing a binary mixture of particles. A three-phase (gas-liquid-solid) fluidized bed was used to study the hydrodynamic characteristics (pressure drop, phase hold up, minimum fluidization velocity, bed expansion and rise bubble velocity) of the particle (glass beads) with different diameters (4,5,6,8, and10) mm using water as liquid phase and air as the gas phase. The experiments were carried out in a 0.115m ID, a 2 m-height vertical Perspex column. The column consisted of three sections (gas–liquid separation, test and gas–liquid distributor). Heat transfer characteristics in three-phase fluidized beds for an immersed vertical cylindrical heater were studied at steady state conditions. Determining experimentally the heat coefficient in Gas-liquid-solid fluidized-beds and studying the influence of some variables, such as particle size, heat flux, heater position and fluidizing velocity. Then Theoretical analysis and CFD simulation of a fluidized bed reactor for prediction of hydrodynamic properties and heat transfer parameters.
