Improvement in Film Cooling Effectiveness Using Single and Double Rows of Holes With Adverse Compound Angle Orientations

Journal of Thermal Science and Engineering Apllications, 2018
Three-dimensional Reynolds-averaged Navier–Stokes equations with shear stress transport turbulence model are used to analyze the film cooling effectiveness on a flat plate having single row of film hole involving cylindrical hole (CH) and laidback hole

Effects of Jet Geometries on Film-cooling Effectiveness

2007
Numerical 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 γ to be 300 and a round-shaped jet orifice respectively.

ENHANCED FILM COOLING EFFECTIVENESS USING TURBULENCE PROMOTER IN COOLING HOLE

Journal of Enhanced Heat Transfer
The film cooling is investigated experimentally and numerically for gas turbine blade cooling. Film cooling performance is vital for safe operation of the blades. By calculating the film cooling effectiveness, the effect of wall roughness through a turbulence promoter inside the cooling hole is evaluated.
