The results show that the effective working volume reduces obviously with the augment of carrier content and airflow rate.
结果表明，随着载体含量和气流量的增大，流化床内有效工作体积明显减小；
Establishes a mathematic model, taking into account the variation of frost density and the decrease of airflow rate caused by frost layer.
针对平肋肋片管式换热器的结霜过程，建立了数学模型，考虑了霜层密度变化和霜层阻力引起空气流量减小等因素。
The result shows that with the same AS pressure and airflow rate, the greater the AS well depth, the greater the radius of influence(ROI), but the air distribution concen.
实验结果表明：在相同曝气压力和流量下，曝气深度越大，影响半径越大，但影响区内的气流分布越稀疏；相反，曝气深度越小，则曝气影响半径越小，但在影响区内空气流线分布越密。
