摘要/Abstract

摘要： 本文以近年来国内外正在研制的航空气心泵为例,从分析其流动过程出发,建立了气-液两相流动的物理模型和数学模型,采用SIMPLE计算思想进行适当地改进和补充,得到了用于旋转流场两相流动的计算方法和相应的计算程序,并用实验加以验证,结果较为满意。计算和实验的误差<13~19%。这种方法不仅适用于气心泵叶轮流场的计算,也可望能用于其他旋转体系内两相或单相流场的计算。

Abstract: In this paper, we calculate the flow in an aircraft vapor-core pump that has been designed and manufactured in recent years. The physical and mathematical model of gas-liquid two phase flow are subjected by analyzing the flow,well known SIMPLE algorithm is used, but modified properly. The numerical method as well as the computer program that can be used in rotating two phase flow are presented. Results of numerical simulation are In agreement With our experiments, with difference less than 13-19%. The method is hopeful for two or single-phase flow calculation of other rotating systems.
