Abstract: This work is an experimental study of film cooling effectiveness on two real-scale turbine vanes in a three-vane annular cascade. The cascade is connected to a high-flow steady compressor to provide the mainstream flow. ...

Abstract: Film cooling was measured on the endwall of a five-vane annular cascade in a blowdown wind tunnel at an exit Mach number of 0.9. The adiabatic film cooling effectiveness was calculated from the partial pressure of oxygen ...

Abstract: The effects of mainstream flow velocity, density ratio (DR), and coolant-to-mainstream mass flow ratio (MFR) on a vane endwall in a transonic, annular cascade were investigated. A blow down facility consisting of five vanes ...

Abstract: This work focuses on the parametric study of film cooling effectiveness on the turbine vane endwall under various flow conditions. The experiments were performed in a five-vane annular sector cascade facility in a blowdown ...
