Film Cooling Effectiveness in High-Turbulence Flow
Journal of Turbomachinery, 1991The mechanisms influencing film cooling effectiveness on a flat plate in high free-stream turbulence using a single row of 30 deg slant-hole injectors are examined. The primary area of focus is the area within 40 diameters downstream of injection. Of interest are blowing ratios for optimum film cooling effectiveness within 10 diameters downstream of ...

Effects of Jet Geometries on Film-cooling Effectiveness
2007Numerical simulations based on control volume method and RNG k-e turbulence model were performed to investigate the flow and heat transfer characteristics of the flat plate film cooling, squirting out from a cone-shaped jet orifice with a diffuser angle of Ī³ to be 300 and a round-shaped jet orifice respectively.

Journal of turbomachinery, 2017
The interaction of flow and film-cooling effectiveness between jets of double-jet film-cooling (DJFC) holes on a flat plate is studied experimentally. The time-averaged flow field in several axial positions (X/dā=āā2.0, 1.0, and 5.0) is obtained through ...

Effect of Shelf Squealer Tip Configurations on Film Cooling Effectiveness
Heat Transfer, 2018Film cooling effectiveness and heat transfer were measured in squealer tip configurations on the blade tip surface. Three different shelf squealer tip geometries were studied: conventional, vertical, and inclined. The experiment was carried out in a wind

Effect of Streamline Curvature on Film Cooling
Journal of Engineering for Power, 1977The effects of streamline curvature on film cooling effectiveness are discussed. Experiments for air discharged through a slot and into a turbulent boundary layer along a flat, convex, and concave surface are described. Adiabatic wall effectiveness measurements on each surface for several blowing rates are presented.
