Research on cooling effectiveness in stepped slot film cooling vane
Journal of Thermal Science, 2016As one of the most important developments in air cooling technology for hot parts of the aero-engine, film cooling technology has been widely used. Film cooling hole structure exists mainly in areas that have high temperature, uneven cooling effectiveness issues when in actual use.

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 film cooling/regenerative cooling on scramjet engine performances
Journal of Propulsion and Power, 1994Film cooling was modeled to allow performance prediction of scramjet engine design. The model was based on experimental results of the compressible mixing layer for the vicinity of the injection slot, and on analytical results of the turbulent boundary layer in the region far from the slot.

Impact on Adiabatic Film Cooling Effectiveness Using Internal Cyclone Cooling
Volume 5: Heat Transfer, Parts A and B, 2011The internal heat transfer of turbine blades can be augmented using cyclone cooling, but the consequential impact on the external film cooling may be significant. To determine these effects, the distribution of adiabatic film cooling effectiveness was measured on the surface of a symmetrical blade model containing a cylindrical leading-edge channel ...
