抄録

It is anticipated that a response of flow rates of lifting water and solid to a change of supplied air becomes complicated especially in a large-scale air-lift pump. Then it is inevitable to grasp unsteady flow in air-lift pumps for lifting solid in consideration of pipe blockage. In this work, a numerical method of unsteady flow was developed; discretized equations were derived by integration of the governing equations based on the drift flux model for gas-liquid-solid three-phase flow over the control volume, and numerical analyses were accomplished using the numerical procedure based on the so-called SIMPLER algorithm. To verify the present method, numerical results were compared with experimental results, which had been obtained with the air-lift system of 200 m depth. The present results show reasonable agreement with the experimental data. Hence the present method can be applicable to an examination of safety operation of air-lift systems.
