Abstract

Implementations of nanomaterials computation in an enclosure and hybrid fuel cell technologies have sparked interest to learn more about the electrically conducting mixed convection of hybrid nanofluids within a square enclosure influenced by a magnetic field and porous medium. This paper assessed the Tiwari-Das model, as well as the magnetic field, thermal conductivity, and porous medium with effective Prandtl number correlations. The influence of internal heat generation or absorption mechanisms is recognized. The governing equations for mass conservation, primary and secondary momentum with momentum equations considering both convective and magnetic influences, energy, and hybrid nanoparticle concentration are non-dimensionalized. Due to the presence of a porous media through suitable scaling transformations. These equations are subjected to wall boundary conditions, facilitating a dimensionless framework for analysing the system's behaviour. The dimensionless nonlinear coupled boundary-constrained differential problem is addressed by employing Harlow-Welch Marker and Cell (MAC) method, which is a finite-difference computational scheme. With physical framework, the impact of parameters like Darcy number
