Effect of Straight and Compound Blade Lean on the Aerodynamic Performance of a High-Pressure Turbine Nozzle Guide Vane under Residual Swirl
The exhaust flow at the outlet of modern lean-burn combustors, which offer reduced NOx emissions for gas turbines, is characterized by hot streaks (HS) and residual swirl that affect the aerothermal performance of downstream high-pressure (HP) turbine nozzle guide vanes (NGVs). Although leaned blades are widely employe...
