For given solids and vessels the entrainment is very sensitive to gas velocity.
對給定的固體顆粒和容器，其夾帶量對氣速非常敏感。 -
Based on simulation results which were satisfied, the effect of bubble diameter on entrainment concentration forcast result was analyzed. the bubble moving rule was found which includs the bubble is escaping upwards along the way, the diameter of the bubble is bigger, the velocity upwards is larger and the bladder remaining near channel bottom is smaller. to make best use of the function of the aerator, the demands of enough air entrainment quantity and suitable air bubble diameter are needed to be satisfied
根據計算結果，對水氣兩相流中氣泡尺寸對摻氣濃度預測結果的影響進行了分析，得到沿程氣泡不斷上逸，氣泡粒徑越大，其上逸速度越大，則留在渠底附近的氣泡越少的氣泡運動規律，提出了摻氣槽的設計，除滿足摻氣量外還應滿足摻氣粒徑要求的工程建議。 -
Moreover, the secondary wall - impingement distance should be properly reduced in order that the bump play a part in the formation of lean mixture with the increase of environmental pressure or density owing to both the increase of air entrainment, momentum losses and the decrease of the spray tip velocity and penetration
而且當壓力或密度較高時，由於噴霧的空氣卷吸量及動量損失增大，貫穿速度降低及貫穿距減小，為使bump發揮作用，應適當減小二次撞壁距離。
