Overall Cooling Effectiveness on a Gas Turbine Vane With Swirl-Film Cooling
Volume 5A: Heat Transfer, 2019Abstract Numerical calculation of conjugate heat transfer is carried out to study the effect of combined film and swirl cooling at the leading edge of a gas turbine vane with a a cooling chamber inside, in which 3-D steady RANS approach with the k-ω SST turbulence model is used.

The cooling system is required to ensure gas turbine can work at high temperature, which has exceeded the material limitation. An endwall cooling test rig was built up to conduct the endwall cooling research. A detailed work was done for analyzing characteristics of endwall heat transfer and discussing the multi-parameter influence mechanism of overall

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 ...

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 ...

Abstract Application of effusion cooling or effusion based compound cooling in the state of art gas turbine combustor is more and more common, especially in aero-engines. A linearly arranged planar optically accessible three-nozzle lab scale combustor equipped with perforated testing plate for cooling is designed.

The overall cooling effectiveness for a turbine airfoil was quantified based on the external surface temperature relative to the mainstream temperature and the inlet coolant temperature. This can be determined experimentally when the model is constructed so that the Biot number is similar to that of engine components. In this study, the overall cooling
