Abstract: A detailed parametric study of filmcooling effectiveness was carried out on a turbine blade platform. The platform was cooled by purge flow from a simulated stator–rotor seal combined with discrete hole filmcooling. The ...

Abstract: Adiabatic filmcooling effectiveness is examined systematically on a typical high pressure turbine blade by varying three critical flow parameters: coolant blowing ratio, coolanttomainstream density ratio, and freestream ...
