Effects of Free-Stream Turbulence Intensity and Blowing Ratio on Film Cooling of Turbine Blade Leading Edge
초록
We used a cylindrical model which simulates turbine blade leading edge to investigate the effects of free-stream turbulence intensity and blowing ratio on film cooling of turbine blade leading edge. Tests are carried out in a low-speed wind tunnel on a cylindrical model with three rows of injection holes. Mainstream Reynolds number based on the cylinder diameter was
