摘　　要：基于Van Leer矢通量分裂方法结合NND格式,构造一种新的矢通量分裂的差分算法.通过对二维非定常Euler方程的数值计算,证明该算法有着较高的计算精度和效率,并能自动捕捉到流场中的激波.Based on the NND scheme and Van Leer flux vector splitting, a new difference algorithm is compatational method given. The two-dimensional unsteady Euler equations are calculated by the algo- rithm presented in this paper, which shows that this method has higher calculation precision and effi- ciency, and can capture shock in the flowfield automatically.

关 键 词：矢通分裂 NND格式 差分格式
