摘要: 采用理论分析和三角翼数值模拟实验相结合的方法,研究了目前常用的CFD计算格式——Jameson中心格式、RoeFDS格式、VanLeerFVS格式、迎风TVD格式等的粘性分辨率,论述了Jameson中心格式和RoeFDS格式在粘性分辨率上具有的优势,以及VanLeerFVS格式和迎风TVD格式在此方面的不足

Abstract: The viscous resolution of different CFD schemes for vortical flows over delta wings has been investigated both numerically and theoretically, which include Jameson's center scheme, Roe's FDS scheme, Van Leer's FVS scheme and upwind TVD scheme. It has been concluded that Jameson's center scheme and Roe's FDS scheme have the best viscous resolutions, while Van Leer's FVS scheme and upwind TVD scheme are not suitable for vortical flow simulations.

Key words: computational fluid dynamics, vortical flow, viscous resolution
