Local Heat Transfer Distributions of Small Impingement Configurations: A Detailed Experimental Procedure Using Transient Heat Transfer Methods

Peter Ott, Alexandros Terzis, Bernhard Weigand

Impingement cooling is widely used in the cooling of turbine airfoils at critical regions where high heat transfer rates are required due to the large local convection coefficients that can be achieved. An accurate determination of local heat transfer dist ...
