The effects on solids holdup of heat exchanger tube, bed height, static pressure drop and average solids holdup of inlet chamber by superficial velocity were studied in different main distributors.
在不同结构形式的主分布器条件下，研究了表观液速对换热管中固含率、下管箱内床层高度、静压降及平均固含率的影响。
With increasing riser height, the average solid holdup at various axial locations of the riser decreases and becomes more uniformly distributed along the riser height.
提升管高度增加，提升管各高度截面上的平均固含率减小，其轴向分布也更加均匀。
The average relative error of gas holdup of the riser between calculated values and experimental values was 6.429%.
