Adiabatic and Overall Effectiveness for a Film Cooled Blade
Volume 2: Turbo Expo 2004, 2004Laboratory studies of film cooling performance for turbine section airfoils typically quantify adiabatic effectiveness and occasionally the heat transfer coefficient for the film cooling configuration. In this study the normalized airfoil metal surface temperatures are obtained directly by using a test model that has a material conductivity scaled to ...

Adiabatic and Overall Effectiveness for a Fully Cooled Turbine Vane
Volume 3B: Heat Transfer, 2013Adiabatic and overall effectiveness data were measured for a fully cooled, scaled up turbine vane model in a low speed linear cascade with a chord-exit Reynolds number of 700,000. The overall effectiveness is a measure of the external surface temperature relative to the mainstream temperature and the inlet coolant temperature, and consequently is a ...

Volume 5C: Heat Transfer, 2016
Adiabatic and overall effectiveness levels were measured in a closed loop linear test section using an inlet Reynolds number of 120,000 for an airfoil model at its designed inlet angle of −30.1°. Two models were used in the study — one made of a low thermal conductivity foam, and one of a higher thermal conductivity material which allowed for the Biot ...

Effects of Using Advanced Cooling Systems on the Overall Power Consumption of Processors
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2013The increase in power dissipation of high-performance computing systems has driven the need for advance cooling systems. Recently, localized spot cooling using embedded thermoelectric coolers (eTECs) and chip-level cooling using miniature-scale refrigeration system have been demonstrated for mitigating thermal and power problems in high-performance ...
