Experimental and numerical study of the anti-crossflows impingement cooling structure

Furthermore, the ACF impingement cooling structure was implemented in a convectively cooled turbine vane and investigated numerically. The results showed that the ACF impingement cooling structure was promising for the vane by improving the performance of vane cooling system. The partial wall temperature of the vane was reduced by 10-30 K with the same pressure drop and mass flow of cooling air.
