| Abstract: | According to the gas purifying process of low Re number of gas-liquid cross flow,provided the conditions which can avoid the liquid entrainment effectively is proposed in the paper.The numerical simulation of fluid dynamics showed that the surface of liquid column changing with the distance at the beginning,the correlation of Lb/d=2.84We0.694can be used to predict the liquid column's break length. |
| Keywords: | gas-liquid cross flow gas purify numerical simulation |
