【摘要】 本文以Ｅｌｇｈｏｂａｓｈｉ和Ａｂｏｕ－Ａｒａｂ提出的固－液两相流动方程作为描述液体相运动的控制方程，以拉格朗日形式下的球形颗粒在液流中的运动方程作为描述固体颗粒相运动的基本方程，建立了固－液两相流中的泡动力方程及在球泡溃灭时间τｃ＊和固体颗粒动力响应驰豫时间τｒｅｌ＊分别为τｃ＊＞＞τｒｃｌ＊和τｃ＊＜＜τｒｅｌ＊两种极端情况下的简化方程。更多还原

【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.更多还原
