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。
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. [
