endwalls with different AR of 0.5, 1 and 2. While present com- pound HTE measure enriches the HTE varieties for general engi- neering applications, the comparative thermal performances interms of Nu=Nu1 , f/f and TPF between present test channels and the typical HTE measures for gas turbine blade cooling can en- lighten the favorable HTE elements with the higher degrees of HTE benefits and/or TPF at the less expense of f augmentations. To as- sist the design activities using present HTE measure, the Nu and f correlations are generated with Re and AR as the controlling parameters.
