RISAeromechanical Optimization of a Winglet Squealer Tip for an Axial Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The possibility of reducing the over tip leakage loss of unshrouded axial turbine rotors has been investigated in an experiment using a linear cascade of turbine blades and by using CFD. A numerical optimization of a ...
Effect of a Combined Hot-Streak and Swirl Profile on Cooled 1.5-Stage Turbine Aerodynamics: An Experimental and Computational Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently developed lean-burn combustors offer reduced NOx emissions for gas turbines. The flow at exit of lean-burn combustors is dominated by hot streaks and residual swirl, which have been shown—individually—to impact ...
