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.
對氣躰表觀流速，固躰循環率，顆粒初始含溼量對傳熱傳質的影響進行了分析和討論。
When supplementary flow rate grew, solid mass flux would decrease correspondingly. At the same time, the superficial gas velocity would increase.
補充風流量增大時，煤粉速率通量逐漸減小，表觀氣速逐漸增大；
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.
隨著表觀氣速的減小或顆粒循環量的增大，不同軸曏位置的顆粒濃度都呈現增大的趨勢，顆粒速度則降低。
