Mathematical Analysis of Convective Heat Exchanger from Renewable Sun’s Radiation through Nano-fluid in Direct Absorption Solar Collectors with the Procreation of Entropy.

Abstract

Now a days the high demand of energy cause the climate change which affect the living style of the people in the world. To mitigate this cases, the usage of renewable energy like solar energy plays a key role. In the application of thermal radiation, the work done is not 100% efficient due to the procreation of entropy. In this investigation, the researchers examined the heat and mass transfer from sun’s radiation through direct absorption into nanofluid with the creation of entropy. The mathematical governed partial differential equations are simplified by the use of similarity transformation variable which yields system of ordinary differential equations. To provide the solution for this problem, the wellknown analytic method called Homotopy Analysis Method implemented on Mathematica 12.1 based on the BVPh2.0 package. The validity of thisresult can be justified by comparing the solutions with different publishedarticles for specific values. From this study, we perceived that the transfer of heat from sun’s radiation is proliferated with multiple production of entropy. Thus, to gain the fruitful usage of renewable solar energy, weneed to maximize the heat transfer and minimize the creation of entropy. Keywords: Convective, Renewable Energy, DASC, Nanofluid, Entropy
