Present numerical investigation proposes to mitigate the effects of Counter rotating vortex pair (CRVP) by employing a pair of vortex generator. Numerical simulation has been carried out to investigate the effect of placement of vortex generator on the characteristics of film cooling effectiveness. Various configuration has been taken based on vortex generator location at upstream, downstream of circular film cooling hole. Along with these utilizing multiple vortex generator at different downstream location also has been detected. The jet to cross flow blowing ratios (M = ρ_ju_j/ρ_cfu_cf) is maintained at unity while Reynolds number based on free stream velocity and film cooling hole dimension is kept at 17,000. The investigation of suitable turbulence model has been studied. The results are compared with baseline case. The numerical investigation is accomplished implementing FLUENT commercial code adopting the K-omega SST model. Among configuration E and all quantity (Density ratio (DR), Blowing ratio (M), Reynolds number (Re) and Turbulence intensity (TI)) better CRVP distribution is depicted for TI and lowest for configuration E.

目前的数值研究提出通过采用一对涡流发生器来减轻反向旋转涡流对（CRVP）的影响。进行了数值模拟，以研究涡流发生器的布置对薄膜冷却效率特性的影响。基于涡流发生器在圆形膜冷却孔的上游，下游的位置采取了各种构造。随着这些技术的发展，在不同的下游位置还利用了多个涡流发生器。喷射到横流吹比（中号 =  ρ _Ĵ Ü _Ĵ / ρ _CF ü _CF）保持一致，而基于自由流速度和薄膜冷却孔尺寸的雷诺数保持在17,000。已经研究了合适的湍流模型。将结果与基准案例进行比较。通过采用K -omega SST模型实现FLUENT商业代码，完成了数值研究。在配置E和所有数量（密度比（DR），吹塑比（M），雷诺数（Re）和湍流强度（TI））中，TI的CRVP分布较好，而配置E的CRVP分布最低。
