本工作的目的是建立一种气液固三相流动系统的数值模拟方法，并确定深海采矿用气举泵性能的估算方法。基于带控制体积的三相流漂移流量模型，通过对偏微分方程组的积分，得到了用于数值分析的有限差分方程组，其数值方法基于Patankar提出的SIMPLER算法。为了验证本文的数值方法，将计算结果与Saito等人和Weber等人用较大气升泵获得的实验结果进行了比较，本方法给出了较好的预测结果。
The purposes of this work are to develop a method of numerical simulation for gas-liquid-solid threephase flow systems and to confirm a method of estimating performance of air-lift pump for deep sea mining. Finite difference equations for the numerical analysis were derived by integration of the partial differential equations based on the drift flux model for three-phase flow with control volumes.The method of the numerical procedure is based on the so-called SIMPLER algorithm proposed by Patankar. To prove the present numerical procedure,calculations were compared with experimental results which had been obtained with the relatively large air-lift pump by Saito et al.and Weber et al.The present method gave good predictions.
