| 摘 要： | 将文「１－３」中的一维时－空守恒格式推广到了二维情形，得到了一般坐标系下的二维Ｅｕｌｅｒ方程时－空守恒格式，并用几个典型算例进行了检验计算，结果表明：本文得到的二维时－空守恒格式保留了一维格式所有的优点，格式简单，通用性强，而且对激波等间断具有很高的分辨率。

| Abstract: | In this paper, the space time conservation scheme developed by the authors in is extended to two dimensional case and a new space time conservation scheme for Euler equations in general coordinate system is obtained. This scheme has all the features as the space time conservation element and solution element method (CE/SE), including its simplicity, generality, high accuracy and high shock resolution. Numerical results of four duct flow problems are given using this scheme. |
