... 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...

... The blade leading edge region is the most susceptible to the high temperature ablation. Film cooling strategy is often used to protect this region from being burned. In this paper, from the view point of heat flux transfer direction, the two simulated heat transfer coefficients method were...

... and the change in heat transfer coefficients ( h f / h 0 ) for the film cooled surface to determine the net heat flux reduction (Δ q r ). Although measurement of Δ q r for laboratory models give an indication of the ultimate film cooling performance, this does not show how much the surface...
