Abstract
Fluid movement and heat transmission inside a rectangular framework have a broad range of technical applications, like generating electricity, nuclear reactors, and power systems. Researchers are now focused on enhancing heat transfer (HT) rates utilizing hybrid nanofluid (HNF). The current study aims to explore the steady, incompressible circulation of hybrid nanofluids comprising aluminum oxide A l 2 O 3 and graphene G N P nanoparticles mixed with water inside a porous rectangular framework. The study investigates the Walter B model flow under the influence of the magnetic parameter. Furthermore, entropy generation, heat transfer, and Bejan number are investigated under the effects of thermal radiation, Joule heating, Cattaneo-Christov heat flux (CCHF) model, and viscous dissipation. Furthermore, the physical quantities are investigated. The nonlinear governing partial differential equations (PDEs) are altered to ordinary differential equations (ODEs) utilizing similarity transformations. The homotopy analysis method (HAM) in Mathematica is then used to solve the dimensionless system of equations. Graphical and tabular results are presented to examine the effects of governing parameters on the flow and thermal characteristics. The results show that greater magnetic factors reduce velocity components, whilst Walters-B parameter increases the secondary velocity but decreases the primary velocity. As magnetic parameters increase, the temperature profile improves, but the skin friction coefficient drops. The Nusselt number increases with Biot number. For increasing Brinkman number the entropy generation increases, while Bejan number decreases.
