摘要 结合一维等熵管流理论,采用CFD方法对某型拉瓦尔喷管典型工作的流场进行整场数值模拟,阐述了网格生成,流场初始化,以及RNG湍流模型使用方法,并对拉瓦尔喷管工作特性进行了气动分析。研究表明,CFD计算结合一维管流理论能明显提高计算效率,数值计算结果与理论相符较好。 Combined with one- dimensional isentropic flow theory, CFD methods are used to simulate the whole flow field of a certain Laval nozzle under the typical operations. The paper describes the gird gener- ation,flow field initialization and RNG turbulence model application;furthermore, it analyzes the nozzle aerodynamic characteristics. Investigations show that computational efficiency is significantly improved by combining CFD with one- dimensional flow theory. The numerical results match well with the theory.
