Simulation of MHD Quadratic Natural Convective Flow of Nanofluid Inside a Square Enclosure with Thermal Radiation Effect

Magnetohydrodynamic quadratic convective flow and thermal transport of water-based nanoliquid inside an enclosure are numerically studied for various values of key parameters. The modeling of the present problem associates with nonlinear partial differential equations that are solved by adopting the efficient numerical technique known as marker-and-cell (MAC) method. The present results are validated with the available literature on convective flow inside an enclosure of square shape. The influence of Rayleigh number, nonlinear temperature parameter, and Hartmann number on convective fluid velocity and thermal transport is scrutinized. The numerical results reveal the features of convective thermal energy distribution of water-based nanofluid inside the enclosure of square shape. It is noted that an upsurge in the nonlinear temperature parameter and Rayleigh number values intensifies the heat transfer rate and energy transport.
