Compressor intercooling has traditionally been employed to reduce compressor work and augment gas turbine output power. Conventional intercooling schemes are usually applied through nonmixed heat exchangers between two compressor stages or by cooling the outside of the compressor casing. Any cooling schemes that may affect the flow field inside the compressors have not been favorably considered...

The article investigates the effect of compressor pressure ratio, turbine inlet temperature and ambient temperature on the performance parameters of an air-cooled gas turbine cycle with evaporative cooling of inlet air. Air f ilm cooling has been adopted as the cooling technique for gas turbine blades. The mass of coolant required for turbine blade cooling is calculated f or a selected range of...

This study explores the principle of producing cold through heat absorption at a temperature lower than ambient temperature, which requires use an endothermic mechanism. Specifically, focuses on evaluating multiple thermoelectric coolers using aluminum water exchangers as means validating proposed correlation series experiments. The system utilizes coolant and cooler coupled with heatsink to co...

Thermal management of batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is essential for effective operation in all climates. This has been recognized in the design of battery modules and packs for pre-production prototype or production EVs and HEVs. Designs are evolving and various issues are being addressed. There are trade-offs between performance, functionality, volum...

A suspended, planar multistage micro thermoelectric (TE) cooler is designed using thermal network model to cool MEMS devices. Though the planar (two-dimensional) design is compatible with MEMS fabrication, its cooling performance is reduced compared to that of a pyramid (three-dimensional) design, due to a mechanically indispensable thin dielectric substrate (SiO2) and technical limit on TE fil...

Wepresent a simple layout of a fast cooling system for liquids in sealed containers utilizing the large temperature gradients of cold nitrogen gas. Our system is optimized for about 20 cylindrical containers of 500 cm, but the setup allows for simple upand down-scaling aswell as the use of arbitrary containers.We have characterized the cooling performance of our system experimentally for temper...

57 Cooling Body Temperature Heat is the byproduct of metabolic reactions, with nearly 75% of energy created released as heat. This paper evaluates two studies investigating the effects of cooling core body temperature on overall strength gains and post-exercise recovery. The first study evaluates the effectiveness of cooling before, during and post-exercise on performance and recovery. Results ...
