摘　　要：导出了计算散装填料层压降的半经验关联式 ,在包括泛点气速的多种空塔气速下 ,对 11种填料的床层压降进行了计算 ,总平均计算误差为 6.710 % ,泛点压降平均计算误差为 7.72 7% 。The semiempirical correlations of pressure drop in disordered packings bed are given. For many superficial velocities with flood point velocity pressure drop of eleven kinds packing was calculated,Total average deviation from testing value is 6.710%, Average deviation of flood point is 7.727%, The accuracy is better than given general chart and Correlations in literature.
