摘要
本文建立了二阶非线性偏微分方程求解的有限差分格式,并给出了求解二维跨音速小扰动方程的数值解法,计算了零攻角二维对称翼型的表面压力分布。计算表明,计算结果与实验值符合较好。
A finite difference scheme for solving second-order non-linear partial differentia! equation is presented and a numerical calculation method for solving the two-dimensional transonic small perturbation equation is also given. Transonic surface pressure distribution over two-dimensional symmetric airfoils at zero attack angle. The results of both calcuiation and expriment show a good agreement with eaqch others.
