摘要 对环形狭缝通道内的环状流建立了分离流模型。应用质量、动量和能量守恒方程 ,加上相应的边界条件和使方程组封闭的经验关系式 ,对环形狭缝通道的内、外液膜厚度、液膜内的速度分布和温度分布 ,以及内。 A separated flow model for predicting two-phase pressure drop and two-phase forced convective heat transfer has been developed for annular flow in narrow annular gap at high mass quality. Conservation equations of mass, momentum, and energy are used to solve thicknesses of the thin liquid films both internal and external velocity distribution and temperature distribution. The model can also predict the heat transfer coefficients changing with the annular gap size and heat flux.
