The present research benefits from the finite volume method in investigating influence of combined turbulators on thermal and hydraulic exergy a parabolic solar collector with two-phase hybrid MWCNT-Cu/water nanofluid. All geometries are produced using DesignModeler software. Furthermore, FLUENT software, equipped SIMPLER algorithm, is applied for analyzing performance hydraulic, efficiency. Eu...

In this research, a practical and theoretical study was conducted to evaluate the performance of parabolic trough collectors (PTCS) length (3 m) width (2.67 for three solar connected in parallel, absorber tube is made stainless steel with an internal external diameter (0.028 m), (0.031 respectively. The 11 m, painted un shiny black paint increase absorption sunlight reduces thermal radiation. w...

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...

Simulated performance of packed bed solar energy storage system is reported in the present paper in continuation with Part-I and Part-II of this paper. The present part of the paper deals with system performance w.r.t. energy consumption by fan to propel air through the bed and thermal efficiency of solar collector. It is observed that energy consumption by fan and thermal efficiency of the col...

Solar energy is an environmentally sustainable energy source as it is clean and inexhaustible. Solar systems are very common and cost-effective, thus, can be used for many home applications. In this paper, a new method is presented to optimize solar systems economically, regarding to energy cost fluctuations. In spite of conventional analyses, in which the inflation is considered constant, ...
