| 摘 要： | 在喷管流动问题的数值模拟中,激波的捕获一直是一个研究的重要方面.本文应用二阶精度Godunov型的PLM格式来求解Euler方程,采用非结构化网格,对喷管内瞬态激波的运动及发展进行了研究,并分析激波运动、反射、衍射及相互作用的规律.计算结果表明,PLM法可以用于非结构网格的喷管流场计算中,所得到的数值解较好地反映了瞬态激波结构的有关特征和信息.

| Abstract: | In the numerical simulation of flows in a nozzle, how to capture shock wave draws much attention. Here,using second_Godunov_type PLM and unstructured grids, Euler equations were solved. At the same time, the propagation and development of transient shock in a nozzle were investigated and the rule of reflection, diffraction and interaction between shock waves was analyzed. The results show that it is feasible to calculate flows in a nozzle with unstructured grids and PLM. The numerical solution satisfactorily illustrates the concerned characters and information of transient shock wave. |
