... coefficient (HTC). The results showed that the adiabatic cooling effectiveness could reach 0.65 with a blowing ratio lower than 0.5. Meanwhile, the heat transfer coefficient ratio (h f /h 0 ) of transpiration cooling was close to 1 with a small blowing ratio at 0.125. A higher HTC ratio was observed...

Paper No: GT2020-14169
... Abstract For convective heat transfer involving multiple sources of different temperatures in the flow field such as in film cooling, the adiabatic-wall temperature, T ad , is used as the reference temperature to define the heat-transfer coefficient (HTC). Studies based on computational Fluid...

... process typically causes disturbances in the flow resulting in an increase in the heat transfer coefficient, and hence increases heat transfer to the surface. Since these are counteracting effects, a measure of the net effect on the surface is needed. The surface metal temperatures for the actual...
