摘　　要：采用一种保持通量守恒的不规则对接网格分区求解中交界面耦合条件的计算方法，结合有限体积法求解了Ｅｕｌｅｒ方程，无粘通量取用ＶａｎＬｅｅｒ分裂格式，构造了一种限制器以实现格式的二阶精度和ＴＶＤ性质，并给出数值算例。An internal coupling condition which can guarantee the conservation of flux on the irregular patched grids for the domain decomposition method is given. The Euler equations are solved by using the finite Volume method combined with van Leer′s flux vector splitting. The TVD character and second order accuracy are realized by adopting a new limiter function. Numerical examples are presented as well.
