Effects of Streamwise Distance and Density Ratio on Film-Cooling Effectiveness for Double-Jet Film-Cooling on a Flat Plate

Volume 5C: Heat Transfer, 2018
Several double-jet film-cooling (DJFC) hole geometries on a flat plate are investigated in this paper. Pressure sensitive paint (PSP) is used to measure the film-cooling effectiveness on the flat plate. The streamwise distance between the DJFC holes varies as s/d = 3.0, 4.0, 5.0, and 6.0, while three different spanwise distance conditions are ...

Adiabatic Effectiveness Measurements of Film Cooling in Supersonic Flow

Journal of Turbomachinery
Abstract High-temperature, high supersonic Mach number flows can be encountered in different innovative propulsion system configurations such as rotating detonation combustors (RDCs) and scramjets, requiring the use of film cooling for the thermal management. For this reason, a clear understanding of the performance of film cooling in

Additive Manufacturing Effects on Turbine Film Cooling Effectiveness

Volume 8: Heat Transfer and Thermal Engineering; Mechanics of Solids, Structures and Fluids
Abstract Modern gas turbines operate at high temperatures to improve power and efficiency, requiring effective cooling strategies like film cooling to protect turbine blades. Additive manufacturing (AM) allows for complex cooling geometries but introduces surface roughness that alters flow behavior and can affect cooling performance ...
