| 摘 要： | 本文利用三维积分边界层法并结合流线法决定涡层型流动分离。由三维不可压湍流边界层方程求得边界层参数后,按流线法计算粘性流线。作为算例,研究了一带迎角的扁长椭球体在不可压缩湍流里的绕流,经与水洞里所观察到的α=15°流型的对比,二者基本一致。

| Abstract: | A 3D integral boundary layer approach is used and coupled with streamline method for determining vortex-layer-type flow separation. The boundary layer parameters are solved by 3D incompressible bouadary layer equation. According to the streamline method viscous streamlines are evaluated. As an example, a prolate spheroid was calculated and water tunnel visualization was made. Numerical results are compared with the same experiment, both are in good agreement. |
