| 摘 要： | 本文描述了用Ｅ—Ｏ型的ＡＤＩ隐式差分格式计算二维、无粘、定常与非定常低频小扰动跨音速流的方法。应用附加时间导数项的物面、尾涡面的边界条件及压力系数表达式和远场无反射边界条件，计算翼型绕其１／４弦长处轴作正弦俯仰振动时，翼面上的非定常压力分布。所得结果与文献［１］比较，具有较好的一致性。

| Abstract: | In this paper, the Engquist-Osher switch implicit ADI algorithm is quoted to calculate two -dimensional inviscid steady and unsteady small-disturbance transonic flow. The appropriate unsteady terms are added to the boundary conditions on body surface and wake.The nonreflectig far- field boundary conditions are chosen for steady and unsteady cases.The computaional results of unsteady pressure distribution on the profile when the profile is oscillated in pitch about its 1/4 axis are in good agreement with ones in reference 1. |
