摘要
采用不同密度的网格 ,利用隐式时间有限差分方法对M6机翼进行了Euler方程解算 ,用Richardson外插评估数值误差 ,就网格密度对人工耗散和解的影响进行了分析。
Various grids density are used to solve Euler Equation by using Beam-Warming's Finite difference method. Error estimates are obtained by using Richardson Extrapolation. The relation between grid density and artifical dissipation has been discussed and the accuracy of various soluations has been analysed .
