Performance Degradation due to Blade Surface Roughness in a Single-Stage Axial Turbine

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 levels of surface roughness significantly influence turbine efficiency and heat transfer. This paper pre...
