摘要
建立了固体颗粒和空泡在不可压缩流体任意流场中运动的Ｌａｇｒａｎｇｉａｎ模型，考虑了浓度等因素对固体颗粒和空泡运动的影响，给出了计算固体颗粒和空泡的数值方法，并模拟了一水泵叶轮中的固体颗粒和空泡运动，得出了水泵叶轮流场中固体颗粒和空泡的运动特性，为分析水力机械的磨损提供了可行的数值模拟方法．
Lagrangian model for the motion of solid particles and air bubbles in the flow field of an arbitrary incompressible fluid is developed.A numerical solution of the motion of solid particles and air bubbles with the influences of the fluid concentration on the motion taken into consideration is given.The motion of solid paraticles and air bubbles in the impeller of a centrifugal pump is numerically simulated and the motion characteristics of solid particles and air bubbles obtained.
