| 摘 要： | 将Euler方程写在包括转子和静子的绝对坐标系下,通过在转—静之间设计一个可以随时间扭动的平行四边形网格计算了二维轴流压气机转—静非定常流场。由于整个方程统一写在动网格下,转—静之间没有使用插值。

| Abstract: | The two-dimensional rotor-stator unsteady flow in an axial compressor is calculated by using Euler equations in absolute frame.The computational grids consist of a rotor grid,a stator grid and a intermediate grid which is designed for the connection of blade rows.The fore-boundary points of this intermediate grid rotate with the rotor blades and the aft-boundary points connect with the stator blades.Since the feature of the moving grid is considered in the Euler equations,so it is unnecesary to use the time-consuming interpolation method for information transmission between rotor and stator blade rows.The results of numerical calculation verify the feasibility of the presented approach for calculation of the rotor-stator unsteady flow. |
