Design Optimization of Blade Tip in Subsonic and Transonic Turbine Stages—Part II: Flow Physics and Augmented Aerothermal Integral Objective Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part I, a companion paper of the two-part article, a subsonic turbine stage and a transonic one conditioned at the same Reynolds number, flow coefficient, loading coefficient and reaction, but two different exit Mach ...
Design Optimization of Blade Tip in Subsonic and Transonic Turbine Stages—Part I: Stage Design and Preliminary Tip Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotor blade tip has significant influence on turbine stage aerodynamics and heat transfer. Most previous efforts have been based on low-speed cascade settings. However, more recent research on transonic blade tips exhibits ...
Application of Multiscale Methodology for Transonic Turbine Blade Tip Cooling Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent research suggests that the cooling flow at transonic turbine tip has several unique flow features such as the strong interaction with the base flow, the acceleration at divergent duct, the strong shock boundary layer ...
