| 摘 要： | 突扩型燃烧室的结构简单可靠,近年来已引起广泛注意。为了计算时均流场和湍动流场,必须考虑迴流区及附面层全方位的压力梯度,给计算方法带来困难。 本文由时均的N—S方程和—ε湍流模型出发,将Patankar解耦技术推广到可压缩流,采用牛顿迭代法和稀疏矩阵技术,由连续和动量方程直接求解压力和速度场,继而获得温

| Abstract: | A confined turbulent flow in a sudden expansion duct is computed by a numerical method of time-averaged Navier-Stokes equations with k-e model. The pressure and velocity are obtained by using Newton's method and sparse matrix techniques. The numerical examples show that the computation results are in satisfactory agrefement with the experimental data. |
