Generating power using an Organic Rankine Cycle (ORC) has the advantage of converting waste energy into useful power. This technology can utilize various low-level heat sources such as biomass, engine heat, geothermal and solar, it significantly reduces thermal pollution well reliance on fossil fuels. In this research, a parabolic collector with tube length 18.12 meters was designed manufacture...

The Florida Solar Energy Center (FSEC), with the support of the National Renewable Energy Laboratory (NREL), has investigated the thermal performance of solar absorbers which are an integral yet indistinguishable part of a building’s roof. The first roof-integrated solar absorber (RISA) system was retrofitted into FSEC’S Flexible Roof Facility in Cocoa, Florida in September 1998. This “proof-of...

In this study, the exergy efficiency of a flat plate solar collector using Al2O3, TiO2, CuO nanoparticles and pure water as base fluid is studied. Solar radiation is selected between 200 to 600 W/m2. The method to determine optimum values of optimization variables has been developed by Genetic Algorithm Toolbox in MATLAB software. Results show by increasing solar radiation the optimized exergy ...

Nowadays the design of large-scale structures can be effectively improved by adoption numerical models. Even if experimental tests still play a fundamental role, methodological approach that combines testing and modelling technique significantly improve understanding matter. This, in fact, would result more reliable optimization process, drastically reducing efforts uncertainties towards implem...
