摘要
本文结合高精度TVD格式的数值通量和时间进展多步法给出了一种求解定常流问题的数值方法。同时给出一些特殊处理来加快数值解的收敛速度。本文用以上方法计算了翼型跨音速绕流问题,结果表明此方法具有分辨率高,收敛速度较快之性质。
A method which Combines the numerical flux of high accurate TVD scheme with multistage method in time approaching is developed to calculate the problems of 2-D steady flow. Some special treatments are given to accelerate convergency. The numerical results of transonic flow over NAG A 0012 airfoil are obtained by this method. They show that this method is high accurate, of high resolut- ion nd time-saving,
