Influence of oblique angle on hydrodynamics of gas-solid fluidization in micro fluidized bed

Micro fluidized bed is a promising reactor for a variety of industrial processes. It is important to understand the hydrodynamics of gas-solid fluidization of the micro fluidized beds with different oblique angles. This study numerically investigated the effects of oblique angle on the fluidization behavior and pressure drop in the micro fluidized beds by Computational Particle-Fluid Dynamics (CPFD) models. The results show that the oblique angle of the bed affects strongly the particles, fluidized gas and pressure distribution in the micro fluidized bed due to strong wall effects. The bed with oblique angle of 0° can achieve better gas-solid contact than the inclined beds. The pressure drops in the micro fluidized beds decrease linearly with increasing oblique angles of the beds when the oblique angles are beyond 15°. The oblique angle of the bed has a great influence on the fluidization behavior and pressure drop in the micro fluidized bed.
