摘要: 基于无限插值理论,将旋翼按桨叶数分为几个子块,然后在桨叶连续公共界面上对接各子块,形成绕整个旋翼流场的三维多块网格。各桨叶子块的流场信息直接通过连续公共界面相互交换,利用非定常欧拉方程求解出整个旋翼流场。发展的动态网格在前飞流场计算中取得了成功。

Abstract: The description of the moving grid-strategy is presented. Based on transfinite interpolation, an O-H type grid around one blade is generated. In each subdomain, the weighting funtion is given to account for the time-variation of its nodes. The multi-block grid modelling the whole rotor is achieved by the construction of grid-blocks around each blade which are connected with coincident nodes on their common boundaries, the flowfield of a rotor is calculated by considering the transport of interface information. The calculated results show that the moving grid possesses feasibility and effectiveness.

Key words: Euler equation, moving grids, rotor, forward flight
