采用覆盖网格分区算法[1] ,求解小马赫数下的可压缩 Navier- Stokes方程 ,详细计算小圆柱控制主圆柱涡脱落的流场结构。主要考察了在 Re≤ 80 0的范围内 ,小圆柱的位置、Re变化等因素对流场结构及其非定常演化过程的影响
Computation of the compressible Navier-Stokes equations at small Mach number with the coverage grid partitioning algorithm [1] is used to calculate the flow field structure of the small cylinder control vortex shedding. Mainly investigated the influence of the position of small cylinder and Re on the structure of the flow field and its unsteady evolution in the range of Re≤80 0
