Fundamental Equations of Turbulent Two-Phase Flow
-
摘要: 本文按照严格的办法,从纳维斯笃克斯方程出发,经过雷诺平均得到了两相流动的雷诺方程组,从更大的程度上包含了一些物理量的湍流脉动乘积的平均项。本文还讨论了两相之间的相互作用力,分散相的压力和压力以外的应力以及两相之间能量交换项的表达式。Abstract: A new set of Reynolds equations for predicting turbulent two-phase flows has been developed by means of Reynolds averaging method on the unsteady laminar equations of two-phase flow. These equations involve average terms of products of turbulent fluctuations in some physical parameters in a large degree.The interaction forces between two phases, the pressures for dispersed phase, extra stresses except for pressure and the expressions for energy interchange between two phases have been discussed.
