| 摘 要： | 本文从Euler方程出发,利用LU-ADI格式对绕二元振动翼型跨声速流场进行了数值模拟。文章中给出了绕NACA0012和NACA 64A 010翼型不同状态的几组数值结果,在同某些实验和其它文献结果基本吻合的前提下,研究了振动对翼型表面压力、激波位置的非定常效应以及其它振动参数对流场非定常效应的影响。

| Abstract: | The dynamic process is numerically simulated on two-dimensional airfoils oscillating sinusoidally. The Euler equations are required to solve with the implicit factored finite difference algorithm (LU-ADI). In this paper, numerical results of NACA0012 and NACA-64A010 airfoils are presented, some of them agree with experimental data and the results of reference4]. By the numerical simulation, some unsteady effects are investigated. |
