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。
In this paper, Baker’s AF3 efficient iterative algorithm is used to improve the finite difference method proposed by Jameson to calculate the non-conservative all-potential potential flow across transonic airfoils. An efficient algorithm for arbitrary transonic airfoil analysis is developed. Many experimental examples show that this algorithm converges fast and the calculation results are in good agreement with Jameson’s original method.
