【摘要】 <正> A new set of Keynolds equations for predicting turbutent two-phase flows has beendeveloped by means of Reynolds averaging method on the unsteady laminar equations oftwo-phase flow.These equations involve average terms of products of turbulent fluctuationsin some physical parameters in a large degree.The interaction forces between two phases,thepressures for dispersed phase,extra stresses except for pressure and the expressions forenergy interchange between two phases have been discussed.更多还原
