| Abstract: | The dynamic eguation of bubbles is established in this peper by taking solid-liquid two-phase flow equation,proposed by S. E. Elghobashi and T. W. Abou-Alab, as the governing equation to describe liquid phase flow, and by taking the motion equation in Lagrange form of spherical particles in liquid flow as the fundamental equation to describe the motion of solid particles. The simplified equations are obtained for two extreme situations and, where is colaspe time of a spherical bubble and is lag time of dynamic response Of solid particles. |
