... is the film cooling hole diameter. Coolant is fed to the film cooling holes in a co-flow configuration, and the results of both the smooth and rib-turbulated channels are compared. At a constant coolant flow rate, enhanced internal cooling was found to provide a 44% increase in spatially-averaged overall...

... of the new design. Further, detailed Nusselt number contours obtained from smooth channels provided a valuable insight into how the rib turbulators should be installed to achieve higher heat transfer enhancement. For both the smooth configurations, post the first passage, the coolant momentum flux...
