掺气槽 meaning in English

aeration slot

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
根据计算结果，对水气两相流中气泡尺寸对掺气浓度预测结果的影响进行了分析，得到沿程气泡不断上逸，气泡粒径越大，其上逸速度越大，则留在渠底附近的气泡越少的气泡运动规律，提出了掺气槽的设计，除满足掺气量外还应满足掺气粒径要求的工程建议。
