摘要
本文从欧拉方程和雷诺平均N-S方程出发,采用Mac Cormack格式,数值模拟了收缩喷管出口边缘奇异性带来的不稳定。计算例子与现有实验符合很好。
The numerical solution of inviscid and viscous flow through convergent nozzles is presented from Euler equation and N-S equation. MacCormack explicit difference scheme is used with an improved artificial viscous term. The method employs the split of zone to overcome the instability near exit of the nozzeles. The results of a typical calculation are in good agreement with experimental data.
