Heat Transfer Augmentation Technologies for Internal Cooling of Turbine Components of Gas Turbine Engines
Figure 19
Comparison 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, including results from investigations after 2003. Globally averaged thermal performance parameters are presented as dependent upon friction factor ratios . Symbol definitions are given in Figure 18.
