Energy Efficiency in Mobile Air-Conditioning—A Survey
Abstract: Abstract In the past decades, it has been observed a significant increase in the global production of vehicles. This situation is more visible in developing countries, like India, Many of these automobiles are equipped with mobile air-conditioning (MAC) systems in order to improve the comfort and security of the occupants. In contrast to these positive characteristics, the MAC systems are also responsible for greenhouse gas emissions and an increase of …

Investigation of free convection heat transfers in an attic shaped eclosure
Abstract: Absrtact Numerical investigation of free convection heat transfers in an attic shaped enclosure with differentially heated two inclined walls and filled with air is performed in this study. The left inclined surface is uniformly heated whereas the right inclined surface is uniformly cooled. There is a heat source placed on the right side of the bottom surface. Rest of the bottom surface is kept as adiabatic. Finite volume based commercial …
