Heat exchange plays a major role in any kind of cooling devices, especially those based on caloric effects. Even though more than 50 prototypes this have been developed hitherto, the impact heat transfer coefficient their performance has not explicitly quantified. In work, we quantify regenerative by analyzing existing experimental data with theory. A linear trend is observed between regenerati...

The green roof technology provides environmental benefits by protecting the base roof membrane of buildings against solar radiation and temperature fluctuations and by helping to reduce building’s energy consumption by direct shading. Although several investigations have been performed to explore the energy performance of vegetated roofs as natural cooling devices, there is a lack of data conce...

Non-azeotropic refrigerant mixtures (NARMs) are investigated for a twotemperature level heat exchange process found in a domestic refrigerator-freezer. Ideal (constant air temperature) heat exchange processes are assumed. The results allow the effects of intercooling between the evaporator refrigerant stream and the condenser outlet stream to be examined in a systematic manner. For the conditio...

In the past, numerous simple thermal indices have been developed in order to describe the complex conditions of heat exchange between the human body and its thermal environment. For cold conditions the approaches consider combinations of temperature and wind velocity, focusing on the turbulent flux of sensible heat with the windchill equivalent temperature as the best example. Heat load conditi...

In this study the performances of various non-circular microchannel heat sinks (normalized with circular shape) have been comparatively analyzed for CuO-water nanofluid and baseline pure water flow. Nusselt number and Poiseuille number for each microchannel and thermo-physical properties of CuO-water nanofluid (viz., thermal conductivity, viscosity, specific heat and density) have been designed...
