| 摘 要： | 本文利用Baker的AF3高效迭代算法,改进了Jameson提出的计算跨音速翼型非守恒全位势流的有限差分方法,研制了任意翼型跨音速分析的高效算法程序。许多试验算例表明,本算法,收敛速度快,且计算结果与Jameson的原方法非常一致。

| Abstract: | The finite difference method proposed by Jameson for computation of transonic nonconservative full-potential flow past airfoils is improved in convergence speed by the use of Baker's AF3 efficient iteration scheme. A computer program is developed accordingly. Many test examples presented show that the computations on a mesh of 128x32 require only several decade iterations in most of cases for convergence and that the results obtained agree very well with those by Jameson's original method. |
