A semi-analytical approach to investigate the entropy generation in a tangent hyperbolic magnetized hybrid nanofluid flow upon a stretchable rotating disk

Abstract

The composite nanoparticles (Fe3O4 & Co) in hybrid nanofluids escalate heat transmission by enhancing thermal conductivity. They are more suitable for solar energy systems due to their improved thermophysical and rheological attributes. Motivated by the above, axisymmetric flow immersed in ethylene glycol-water hybrid nanofluid (HNF) with base fluid is normally spread upon a stretchable spinning disk. Physical effects like Ohmic dissipation, nonlinear thermal radiation, heat dissipation, and entropy analysis are also utilized. Hybridization is done by imposing the two-different nanoparticles such as Fe3O4 & Co. The ODEs are generated by applying relevant similarity variables. The ensuing transformed ODEs are tackled semi-analytically with the Homotopy Analysis Method (HAM). It has been determined and quantitatively examined how the different embedded thermo-physical factors influence the velocity and temperature graphically.The study observes that, the radial and azimuthal velocity portfolio decreases with magnetic parameter and power law index accumulations. The Bejan array is lowered due to advances in Brinkmann and magnetic parameters, while the Entropy array is boosted. Furthermore, The heat transmission of an HNF is greater than that of a mono NF. A case study comparison between our findings and those published in the literature reveals a high degree of agreement. The Homotopy analysis investigation of two different nanoparticles such as Fe3O4 & Co with EG base in the presence of Heat, Ohmic dissipation and entropy analysis has not been investigated yet in the available literature.
