In order to study the effect of impingement hole location on the ICE (Integrated Cooling Effectiveness) of turbine vanes, the heat transfer experiments of vanes with low thermal conductivity were conducted. The test vanes include typical film cooling without jets (Vane 0), typical impingement/film cooling with centerline normal jets (Vane 1), and swirl

Fundamental Behaviors and Limits of Impingement Cooling
Twenty-Third Annual IEEE Semiconductor Thermal Measurement and Management Symposium, 2007Direct fluid impingement on a surface has been shown to generate very high performance heat transfer. Several systems have been designed and commercialized incorporating impingement cooling, such as single and multiple jets, sprays and combined jet-drain arrays.

Jet impingement cooling of a convex semi-cylindrical surface
International Journal of Thermal Sciences, 2001Liquid crystals are used to investigate the effect of high relative curvature on surface heat transfer for a round air jet impinging perpendicularly on a semicylindrical convex surface.The relative curvature, ( d/D), is varied by changing the jet tube diameter for the same surface diameter. Relative curvature varies from 0.18-0.38.
