摘要
本文研究了非均匀射流在二维管道内的钝头体绕流问题。所采用的Godunov格式适合于不规则区域上双曲守恒系统的流场计算,数值计算的结果给出该流场的主要特征和激波结构,对于认识这一物理现象和了解波的运动规律是有帮助的。
In this paper, the problem of nonuniform jet flowing around a bluff body in a two-dimensional tube has been studied. The Godunov scheme used in this paper is suitable for the flow field calculation of hyperbolic conservative system in irregular calculation region. The results of numerical simulation show the main features of flow field and the forming process of shock structures and are useful for understanding this physical phenomenon and the law of shock motion.
