RISDetailed Heat Transfer Distributions in Engine Similar Cooling Channels for a Turbine Rotor Blade With Different Rib Orientations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed Nusselt number distributions are presented for a gas turbine engine similar internal channel geometry used for cooling a modern first stage rotor blade. The cooling design has one leading edge channel and a threepass ...
Film Cooling Performance of Antivortex Hole on a Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Improved film cooling performance and coolant flow usage have a significant effect on overall engine performance. In the current study, film cooling performance of an improved antivortex or tripod hole geometry is evaluated ...
Film Cooling Performance of Tripod Antivortex Injection Holes Over the Pressure and Suction Surfaces of a Nozzle Guide Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film cooling performance of the antivortex (AV) hole has been well documented for a flat plate. The goal of this study is to evaluate the same over an airfoil at three different locations: leading edge suction and pressure ...
