In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...

In the present study, a zero-dimensional thermal model has been developed to analyze novel low concentration photovoltaic-thermal (CPVT) collector. The by driving heat transfer and energy balance equations for each part of collector then solving all simultaneously. Moreover, Monte-Carlo ray-tracing software used optical stimulations parabolic trough solar CPVT experimentally tested at Gävle Uni...

The heat transfer characteristics of the working fluid passing through absorber a solar parabolic trough collector (SPTC) can be enhanced by creation turbulence effect. Therefore, novel idea was implemented introducing corrugated tube (CT) instead plain in collector. enhancement improved further use conical strip inserts inside SPTC. A receiver with pitch 8 mm and corrugation height 2 used thre...

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...

The present study reports a novel concept of a direct solar thermal collector that harnesses the localized surface plasmon of metallic nanoparticles suspended in water. At the plasmon resonance frequency, the absorption and scattering from the nanoparticle can be greatly enhanced via the coupling of the incident radiation with the collective motion of electrons in metal. However, the surface pl...

Abstract The mathematical modeling of hybrid nanofluid flow and heat transfer with entropy generation toward parabolic trough surface collector (PTSC) inside the solar-powered ship (SPS) is performed. model used non-Newtonian Oldroyd-B amidst a constant inclined magnetic field influence being considered. then reduced by adopting appropriate similarity transformation into higher-order nonlinear ...

Abstract—Solar water heating is a thermodynamic process of heating water using sunlight with the help of solar water heater. Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other tha...
