摘要
气泡聚并对气泡运动速度和形状有重要影响,本文通过实验探究气泡聚并过程以及不同因素对于聚并的影响。经过多次实验得出,在相同的实验条件下,氮气的聚并时间小于空气气泡的聚并时间。液体浓度增加,气泡聚并时间增大。气泡直径的增加,加大了液膜的体积,增加了液膜脱落时间。
Bubble coalescence has important influence on bubble motion velocity and shape. In this paper, the bubble coalescence process was studied as well as the influence of different factors on the coalescence by experiments. The experiment results show that, nitrogen coalescence time is less than the air bubble coalescence time under the same conditions; the bubble coalescence time increases as liquid concentration increases. With increasing of bubble diameter, the volume of liquid membrane increases, which finally causes the increase of liquid film fall-off time.
