RISImproving the Performance of a Turbine With Low Aspect Ratio Stators by Aft-Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental data and numerical simulations are presented from a research turbine with low aspect ratio nozzle guide vanes (NGVs). The combined effects of mechanical and aerodynamic constraints ...
The Interaction of Turbine Inter-Platform Leakage Flow With the Mainstream Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Individual nozzle guide vanes (NGV’s) in modern aeroengines are often cast as a single piece with integral hub and casing endwalls. When in operation, there is a leakage flow through the ...
