  5. 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。
