RISPerformance Degradation due to Blade Surface Roughness in a Single-Stage Axial Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine blades experience significant surface degradation with service. Previous studies indicate that an order-of-magnitude or greater increase in roughness height is typical, and these elevated ...
Investigation of Three-Dimensional Unsteady Flows in a Two-Stage Shrouded Axial Turbine Using Stereoscopic PIV—Kinematics of Shroud Cavity Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental study of the behavior of leakage flow across shrouded turbine blades. Stereoscopic particle image velocimetry and fast response aerodynamic probe measurements ...
