Abstract: In a flat-plate ejection model, vortex generator（VG） was used to simulate the complex near-wall vortex flow in the cascade flow field, and adiabatic film cooling effectiveness and the change rate of film coverage area of fan-shapedand NEKOMIMI holes were studied. The robustness of fan-shaped and NEKOMIMI holes was analyzed in near-wall vortex current environment. Results show that the streamwise vortex is mixed with the anti-kidney vortex downstream of the film hole, thus lifting the anti-kidney vortex and reducing the film cooling efficiency. NEKOMIMI film hole produces more stable anti-kidney vortex which prevent it to be rolled up by the near-wall vortex. Within the blowing ratio range from 1.0 to 2.0, the area-averaged cooling efficiencies of fan-shaped hole and NEKOMIMI hole are respectively decreased by 9.3%-12.9% and 1.0%-2.7%. The effective coverage is reduced by 14.2%-29.0% for the fan shaped hole while 1.9%-4.6% for the NEKOMIMI hole. Therefore, NEKOMIMI hole has performed better robustness in a complex flow with streamwise vortex.
