RISThree Dimensional Blade Stacking Strategies and Understanding of Flow Physics in Low Pressure Steam Turbines—Part II: Stacking Equivalence and Differentiators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimization of blade stacking in lowpressure (LP) steam turbine development constitutes one of the most delicate and timeconsuming parts of the design process. This is the second part of two papers focusing on stacking ...
Three Dimensional Blade Stacking Strategies and Understanding of Flow Physics in Low Pressure Steam Turbines—Part I: Three Dimensional Stacking Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimization of blade stacking in the last stage of lowpressure (LP) steam turbines constitutes one of the most delicate and timeconsuming parts of the design process. This is the first of two papers focusing on the stacking ...
The Effect of Clearance on Shrouded and Unshrouded Turbines at Two Levels of Reaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effect of seal clearance on the efficiency of a turbine with a shrouded rotor is compared with the effect of the tip clearance when the same turbine has an unshrouded rotor. The shrouded versus unshrouded ...
Improving Intermediate Pressure Turbine Performance by Using a Nonorthogonal Stator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intermediate pressure (IP) turbines in high bypass ratio civil aeroengines are characterized by a significant increase in radius and a low aspect ratio stator. Conventional aerodynamic designs for the IP turbine stator ...
