Humans in everyday life really need energy. Energy use is expected to be sustainable, safe and clean. Solar a renewable energy source that sustains on earth, it can utilized through photovoltaic solar thermal systems. systems capture used directly for water heating purposes. So an environmentally friendly heater created. This heater. Another problem the temperature setting hot still manual, cau...

The biggest problem faced by the world these days is pure drinkable water, and in a few years, water will not be easily available, as it becoming brackish saline due to pollution. By using solar energy, still can produce which used for drinking, cooking, also industrial purposes. In this research, based on clean technology energy drive system that operated with an approximately negligible maint...

Solar collector (Air heater) has low thermal efficiency due to the low thermal conductivity between Air and absorber plate. So there is a need to enhance the thermal conductivity between air and absorber plate. This leads higher temperature to absorber plate and hence maximum thermal losses occurs to environment .It can be made possible by creating artificial roughness on absorber plate .There ...

ABSTRACT: In this paper, the thermal characteristics of single and double flow plane solar heaters with radiating working gas were analyzed and compared by numerical analysis for the first time. The laminar mixed convection gas flow in the heaters was numerically simulated by the CFD method using the finite volume technique. The set of governing equations included the conservation of mass, mome...
