Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC...

The temperature of an electronics device rises fairly linearly with increasing device heat flux. This relationship is especially problematic for defense electronics, where heat dissipation is projected to exceed 1000W/cm in the near future. This paper study explored the benefit of cooling the electronics device using indirect refrigeration cooling system .In this system the heat sink in a prima...

In this study, a new metal hydride heat pump system driven by an electrochemical compressor was proposed.The system uses the electrochemical compressor to generate absorption heating and desorption cooling in two identical LaNi5 reactors operating at different pressure levels. A thermodynamic model was developed to predict the system performance in terms of various parameters. Modeling shows EC...

Utilization of wasted heat instead of fuel combustion is effective to reduce primary energy consumption for mitigating global warming problem. Because wasted heat sources are not necessarily located close to areas of heat demand, one of the difficulties is that wasted heat has to be transferred from heat source side to heat demand side, which may require heat transportation over long distance. ...

Micro-scale devices based on the Stirling cycle are an attractive choice for chipand board-level electronics. A new Stirling cycle micro-refrigeration system composed of arrays of silicon MEMS cooling elements has been designed. COMSOL is used to evaluate the thermal performance of the system. Simulation of compressible flow and heat transfer with a large deformed mesh has been successfully imp...

We present the temperature dependence of absorption and reduced scattering coefficients of 1.8% Intralipid measured by frequency-domain photon-migration spectroscopy between 710 and 850 nm. These measurements were made in the physiologically relevant 30 to 40 degrees C temperature range. The temperature coefficients for absorption were consistent during heating and cooling and follow closely ot...

Aero gas turbine engines have been using mainly film cooling and convection cooling techniques. For operating at high gas temperature amongst different cooling options the transpiration cooling technique has emerged as the most promising technique to improve the gas turbine cycle performance by allowing higher turbine inlet temperatures. This paper investigates the advantages of transpiration c...
