superficial mass velocity

基本解释

The effect of air superficial velocity, solid rate and initial moisture content on the heat and mass transfer were discussed.
对气体表观流速，固体循环率，颗粒初始含湿量对传热传质的影响进行了分析和讨论。
When supplementary flow rate grew, solid mass flux would decrease correspondingly. At the same time, the superficial gas velocity would increase.
补充风流量增大时，煤粉速率通量逐渐减小，表观气速逐渐增大；
With the decreasing of superficial gas velocity or increasing of solid mass flux, solid volume fraction at different axial positions increases simultaneously, while the particle velocity decreases.
随着表观气速的减小或颗粒循环量的增大，不同轴向位置的颗粒浓度都呈现增大的趋势，颗粒速度则降低。
