-
摘要: 在结构网格下,从三点迎风紧致逼近出发提出了一种适合于有限体积离散的恢复函数生成办法,在光滑区它具有三阶精度,并且在捕捉激波时有较高的激波分辨率。文中完成了典型算例。Abstract: A new reconstruction method for the difference of primitive function derivation is developed on structure meshes.Such a scheme is based on a finite volume discretization.It achieves 3-order spatial accuracy with upwind compact difference.Numerical experiment of transonic channel flow is presented and discussed.
