流れ制御片側デバイスのフィルム冷却性能に関する研究

抄録

The study proposes a new flow control device (FCD), called one-side FCD or OFCD, to Improve conventional cooling hole film effectiveness of turbine airfoils for gas turbine. Experimental examinations are conducted using PSP (Pressure-Sensitive Paint) method to verify the predictability of film effectiveness by the present calculation. It is found that OFCD performs fairly well.
