| 摘 要： | 文中抛弃传统的换热器两相区简单均相流模型 ,采用三相双流体模型 ,在合理假设的基础上 ,针对风冷冷凝器可能出现的流型 ,分别建立相应的控制方程。在保证质量、动量和能量守恒基础上 ,考虑相应气液界面关系 ,联立求解。并以 R1 2为矿物油、R1 34a与 P.A.G.油为例 ,分析不同含油率情况下对换热和流动的影响

| Abstract: | Three-phase, two-fluid model is used in this paper and the conventional simple homogeneous model is discard in two-phase flow of heat exchanger. Control equations are built on the basis of rational hypotheses for the probable flow patterns in air condenser and the relation between liquid and vapor is considered. Using R12 with oil, R134a with P.A.G.as examples, analyse the lubricating oil effects on heat transfer and pressure drop. |
