Boundary-Layer Transition and Separation Near the Leading Edge of a High-Speed Turbine BladeSource: Journal of Engineering for Gas Turbines and Power:;1985:;volume( 107 ):;issue: 001::page 127Author:H. P. Hodson

Abstract: The state of the boundary layers near the leading edge of a high-speed turbine blade has been investigated, in cascade, using an array of surface-mounted, constant-temperature, hot-film anemometers. The measurements are interpreted with the aid of inviscid and viscous prediction codes. The effects of Reynolds number, compressibility, incidence, and free-stream turbulence are described. In all cases, the initial development of the boundary layers was extremely complex and, even at design conditions, separation and reattachment, transition and relaminarization were found to occur.
