Film cooling is widely applied as an effective way to maintain the turbine blade temperature at acceptable level. The present paper investigates overall effectiveness and flow structure by performing conjugate heat transfer simulations for flat-plate baseline cylindrical three cratered film-cooling holes. in fluid domain obtained using Shear Stress Transport turbulence model, solid conductivity...

The liquid droplet cooling technique for fast scanning chip calorimetry (FSC) is introduced, increasing the rate large samples on a given sensor. Reaching higher rates and using gas as medium, common standard ultra-fast temperature control in requires reducing lateral dimensions of sample maximum limited by heat capacity exchange between sample. enhanced performance new demonstrated both metals...

Passive radiative cooling materials that spontaneously cool below ambient temperature can save tremendous amounts of energy used for applications. A multitude materials, structures, and fabrication strategies have been reported in recent years. Important material parameters like a tailored or broadband emissivity, angle selectivity, the influence nonradiative heat losses were discussed detail. ...

This paper describes the theoretical and experimental investigations of the key components and also the performance analysis of a rotary wheel for using as a solid desiccant dehumidifier and also indirect evaporator cooling system. Solid desiccants have long been used in dehumidification and cooling systems for energy efficiency or reduce electricity. Although many mathematical models on th...

We report laser-induced cooling with thulium-doped BaY2F8 single crystals grown using the Czochralski technique. The spectroscopic characterization of the crystals has been used to evaluate the laser cooling performance of the samples. Cooling by 3 degrees below ambient temperature is obtained in a single-pass geometry with 4.4 Watts of pump laser power at lambda = 1855 nm.

Title of Dissertation: On-Chip Thermoelectric Cooling of Semiconductor Hot Spot Peng Wang, Doctor of Philosophy, 2007 Directed By: Professor Avram Bar-Cohen Assistant Professor Bao Yang Department of Mechanical Engineering The Moore’s Law progression in semiconductor technology, including shrinking feature size, increasing transistor density, and faster circuit speeds, is leading to increasing ...

The main challenge for the practical application of metal hydride heat pump (MHHP) is the relatively poor system performance, which is mainly caused by the undesirable heat transfer performance of reaction bed. However, there is no significant improvement of system performance when enhancing the effective thermal conductivity (E.T.C) of reaction bed. In order to identify the relationship betwee...
