RISExperimental and Numerical Investigations of Shock Film Cooling Interaction on a Turbine Blade With Fan Shaped Cooling Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the findings of an experimental and numerical investigation on the shock effect on heat transfer coefficient and filmcooling effectiveness. In this study, coolant was injected on the blade surface through ...
Heat Transfer Performance of a Showerhead and Shaped Hole Film Cooled Vane at Transonic Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was performed to measure surface Nusselt number and film cooling effectiveness on a film cooled first stage nozzle guide vane (NGV) at high freestream turbulence, using a transient thin film gauge ...
Numerical Investigation of Aerothermal Characteristics of the Blade Tip and Near Tip Regions of a Transonic Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In modern gas turbine engines, the blade tips and neartip regions are exposed to high thermal loads caused by the tip leakage flow. The rotor blades are therefore carefully designed to achieve optimum work extraction at ...
An Experimental and Numerical Study on the Aerothermal Characteristics of a Ribbed Transonic Squealer Tip Turbine Blade With Purge Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed heat transfer coefficient (HTC) and film cooling effectiveness (Eta) distribution on a squealertipped first stage rotor blade were measured using an infrared technique. The blade tip design, obtained from the Solar ...
