Abstract: The ability to understand and predict the pressure losses of orifices is important in order to improve the air flow within the secondary air system. This experimental study investigates the behavior of the discharge ...

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: 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 ...

Abstract: Recent technological advances in the field of additive manufacturing have made possible to manufacture turbine engine components characterized by controlled permeability in desired areas. These have shown great potential ...
