Frontiers in Heat and Mass Transfer (FHMT) 20 - 27 (2023)

Renewable solar energy mitigates climate change problem and satisfy high demand of energy. Practically, because of entropy procreation, it is not 100% efficient. So, in this investigation, researchers examined heat and mass transfer through nanofluid from sun’s radiation in direct absorption solar collector with entropy creation. Mathematical governed partial differential equations are simplified by similarity transformation variable which yields system of ordinary differential equations. Resulting mathematical system is solved by well-known analytic approach called Homotopy Analysis Method applying BVPh2.0 package on Mathematica 12.1. Validations justified through comparison. Hence, heat transfer from sun’s radiation is proliferated with multiple production of entropy.
