摘要: 提出一个用自适应流线网格计算定常超声速流场的数值方法。Friedrichs-Lax格式推广到任意四边形网格,在迭代过程中得到速度场后,从流线方程计算流线的位置,最后算出由本方法得到高分辨率结果

Abstract: A numerical method of computing steady supersonic flow fields by using adaptive streamline grids.The Friedrichs-Lax Scheme is extended to arbitrary quadrilateral grids.during itaration process the streamline positions are computed from streamline equation after the velocity field is obtained.Finally,the high resolution results obtained by the method are shown.

Key words: adaptive, streamline grids, Finite volume friedrichs-Lax scheme, Supersonic flow
