Comparisons of relative performance of rib turbulators, pin fins, swirl chambers, dimple-smooth arrangements, dimple-protrusion arrangements, dimple-dimple arrangements, surface roughness, and smooth-walled channels [1], with results from rotation experiments [128, 173]. Globally averaged thermal performance parameters are presented as dependent upon friction factor ratios .
