Abstract: In this paper, the transient IRthermography method is used to investigate the effect of showerhead cooling on the filmcooling performance of the suction side of a turbine guide vane working under enginerepresentative ...

Abstract: An experimental investigation on a cooled nozzle guide vane (NGV) has been conducted in an annular sector to quantify aerodynamic influences of shower head (SH) and trailing edge (TE) cooling. The investigated vane is a ...

Abstract: The cooling air flow in a gas turbine is governed by the flow through its internal passages and controlled by restrictors such as circular orifices. If the cooling air flow is incorrectly controlled, the durability and ...
