摘要
本文将经作者改进后的一维时－空守恒格式推广到了二维情形，得到了一个一般形式的二维Ｅｕｌｅｒ方程时－空守恒格式，该格式对各种不规则几何区域内的流动问题具有很强的适应性，同时它还保留了一维格式的优点。几个典型算例的计算结果表明，本文格式不仅精度高，通用性好，而且对激波等间断具有很高的分辨率。
In this paper, the 1 D space time conservation scheme modified by the author is extended to two dimensional ones and a general form of space time conservation scheme for 2 D Euler equations is obtained. This scheme is flexible and can be used in the computation of many flow problems. Of course, it has all the features which the space time conservation element and solution element method (CE/SE) has. Four complex flow problems are calculated using this scheme and the numerical results agree well with the experimental ones. It is also show that the scheme has high accuracy and high shock resolution.
