In this paper, artificial neural networks (ANNs) and genetic algorithms (GAs) are used for the design of solar flat-plate collectors. It is proved in this paper that by using the Taguchi method for selecting the data required for training the ANN is very effective in allowing the network to learn the behavior of the system satisfactorily. The parameters on which the flat-plate collector design ...

in this research a flat plate solar air collector was investigated under direct solar radiation consisted of a slatted glass cover, perforated absorber aluminum sheets (porosity 0.0177, 0.0314 and absorber thickness of 2.5 mm). the effect of porosity on absorber efficiency of collector was evaluated. six levels of air mass flow rates (0.0056 to 0.0385 kg m-2 s-1) were adopted.average solar ener...

The article is devoted to the thermal calculation of a flat plate solar collector. In this case, boundary conditions are third kind. solution found in transition an elliptical coordinate system. author has obtained analytical for distribution temperature field collector with cross-section at zero ambient partial adiabatic isolation form functional series using hypergeometric functions.

The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...

outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

The influence of recycling on double-pass solar air collectors with welding of the V-corrugated absorber has been studied experimentally and theoretically. Welding the V-corrugated absorber and the recycle-effect concept to the solar air collector was proposed to strengthen the convective heat-transfer coefficient due to turbulence promotion. Both the recycle effect and the V-corrugated absorbe...

Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...

Exploitation of solar energy for achieving low temperature is an active area of research at present owing to the concern over suitable alternatives to synthetic refrigerants and large electricity consumption by conventional vapour compression systems. Present work theoretically design and analyze the performance of a solar flat-plate collector-driven water-Lithium bromide absorption refrigerati...
