气泡泵垂直提升管内气泡运动的CFD数值模拟研究
CFD Numerical Simulation Analysis of Bubble Motion in Vertical Lifting of Bubble Pump
摘要
Abstract
At present,the research of the bubble pump mainly concentrates on the influence of the heating power,the diameter and the number of tubes on the bubble pump,while the research on the bubble motion in the vertical lift tube is less.The CFD numerical simulation on the bubble generation and movement in the double and three vertical lifting tubes of the bubble pump were simulated by the VOF model.The results show that the number of tubes has no effect on the formation and movement of bubbles in the low heating power range.In the high heating power,the liquid lifting capacity in the volume of liquid increases with the increase of the vertical lifting tubes,but it does not have a corresponding multiplied increase.The ammonia water is suitable to be used as the working fluid of the bubble pump,when the number of the lifting pipe is the same at 0.4 MPa pressure.The conclusions are obtained that improving the structure of the bubble pump,selecting the appropriate heating power and working fluid will be a trend of the development of the bubble pump.关键词
