... 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...

... 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...

... Abstract The heat transfer coefficient (HTC) is one of the key parameters that should be known at the stage of the bearing chamber design. This ensures safe temperature conditions for the lubrication oil and reliable operation of the gas turbine engine. The temperature gradient method...

... The Inverse Flux Solver for Arbitrary Waveforms (IFSAW) algorithm is a transient, simultaneous solution of time resolved adiabatic effectiveness, η ( t ), and heat transfer coefficient, h ( t ). Numerical simulations showed IFSAW maintained its high accuracy despite two experimental sources...

... coefficients method were compared. It was found that, for the present study, the conventional method of using same jet and main flow temperature (i.e. the isothermal method) to obtain film cooling heat transfer coefficient is not adequate and can not reflect the heat transfer phenomenon in film cooling...

... 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...
