摘要
在Zenz型相图上对气力输送方式进行分类是以气体表观速度作为分类标准的,由上文(1)知,对水平管输送,以沉积速度u_s和临界速度u_c为划分界限值;对垂直管噎塞型输送,以噎塞速度u_(ch)和最小流化输送速度u_m为划分界限值.
The correlations for demarcating critical values in the Zenz-type phase di agram, i. e., saltation velocity, critical velocity, choking velocity and minimum velocity of fluidization are discussed in details and the correlations apppropriate for the purpose of design are recommended. Topics for further research are suggested to achieve accurate classification.
