摘要
描述了三维Euler方程数值模拟旋翼悬停流场的过程。欧拉方程的求解采用了网格中心有限体积法,五步Runge-Kutta时间推进格式。在没有建立尾迹模型的前提下,计算了两叶旋翼在亚、跨声速时的压强分布,并将计算结果与国外实验数据作了对比,二者吻合程度良好。
A numerical procedure is presented for calculating the flowfield over a lifting and nonlifting rotor in hover.The approach is to solve the inviscid compressible Euler equations in a rotor fixed frame of refrence using a finite volume method and Runge Kutta scheme.Without any wake model,the pressure distributions are presented for two bladed rotor,the theoretical results show good agreement with experiment data.
