Effect of the Angle of the Inclined Perforated Plates on Gas-flow Behavior in a Z-path Moving Bed
折流式移动床中不同分布板倾角下气相流动行为的数值模拟

k-( turbulence model and Ergun equation is applied to simulate the gas-flow behaviour in a Z-path-moving bed. Especially, the effect of the angle of the inclined perforated plates was investigated. The simulation result was agreed well with the experimental data, which demonstrated the reliability of the model. The simulation disclosed that, in a Z-path moving bed, with the enlargement of angle of the inclined perforated plates, the pressure drop reduced and the fact that gas flow towards the high end of the above perforated plate was enhanced.
