Experimental convective heat transfer investigation around a film cooled high pressure turbine blade
Abstract
This paper deals with an experimental heat transfer investigation around a film cooled, high pressure gas turbine rotor blade. The measurements were performed in the von Karman Institute short duration isentropic light piston compression tube facility using platinum thin film gauges painted on a blade made of machinable glass ceramic. The coolant was ejected simultaneously through the leading edge (3 rows), the suction side (2 rows) and the pressure side (1 row). The coolant hydrodynamic behavior is described and the effects of overall mass weight ratio, coolant to free stream temperature ratio and free stream turbulence are successively investigated.
