| Abstract: | 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. |
