Abstract

The need for clean energy in today's world is increasing day by day due to the limited nature of fossil resources. Solar energy can be utilized in various domestic, agricultural, and industrial applications. Integrated solar storage collectors are extensively used for generating heat by absorbing solar energy and converting it into thermal energy. Therefore, there is a significant need to design and produce these collectors to achieve the highest performance and efficiency. In this research, considering a type of integrated solar storage collector and using the hybrid nanofluid MWCNT-Fe3O4, its effect at different Rayleigh numbers (103-106) and various nanofluid percentages (0-0.003) has been investigated. Velocity and temperature contours and streamlines in different positions of the hot absorber inside the collector have been examined. The local and average Nusselt numbers have also been studied. The results indicate an increase in heat transfer at the Rayleigh number and a high percentage of nanofluid. Additionally, the optimal position for placing the hot absorber is at the far right end of the collector. The results of this research are published for the first time and can be used for designing solar collectors.
