The present article deals with the incompressible magnetohydrodynamic (MHD) hybrid nanofluid flow through a heated enclosure containing a non-Darcy porous medium. Employing non-Darcy-based model, the non-dimensional governing mass, energy and momentum equations associated with boundary conditions have been solved by suitable transformations and D2Q9-based Lattice Boltzmann Method via MATLAB. At fixed value of Pr, the present analysis has been done considering the variation in Hartmann number (Ha), heat generation (Q), Rayleigh number (Ra), thermal radiation (Rd), and Darcy number (Da) to numerically explore the influence of MHD nanofluid flow on considered geometry in terms of temperature contours, streamlines and Nusselt number distributions. It has been observed that the increase in the values of Ra causes the increase in the length of vortex diagonally. In addition, a linear relationship has been found between the values of Ra and the magnitude of Nusselt number. Furthermore, it has been found that the trend of local Nusselt number decreases with the increase in the values of Ha.
