Abstract

Research was conducted to assess the heat transfer performance within a typical leading-edge cooled aerofoil geometry. The geometry focuses on an array of film holes impinging on a concave target surface. For this comparison, a single set of specified Reynolds number, jet to target spacing, jet to jet spacing, and concave surface parameters, two locations of impingement nozzle position were tested. Experimental heat transfer coefficient data shows that with these parameters, the jet to target effects of nozzle position primarily drive the heat transfer coefficient. Experimental Nusselt number distributions show the effects of the nozzle position relative to the concave, and are supported by numerical modelling.
