Abstract
The present analysis is performed to investigate the free convection MHD non-Darcy
flow in hybrid nanofluid (TiO2/Cu-water) occupying a differentially heated square closed
space. The non-dimensional governing equations for mass, momentum and energy are solved
under boundary conditions by using the D2Q9-based Lattice Boltzmann Method. A key novelty
of the work is the inclusion of an RSM-based sensitivity analysis. The current investigation has
been done considering the variation in Rayleigh number (103 ≤ Ra ≤ 106
), Darcy number
(0.0001 ≤ Da ≤ 0.1) and Hartmann number (0 ≤ Ha ≤ 50). It has been shown that the diagonal
length of an eddy is boosted as the Rayleigh number increases. In addition, it has been shown
that the Nusselt number tends to drop as Ha values rise. From RSM, high Darcy parameter,
low volumetric fraction and low Hartmann number are identified as the optimum functioning
conditions for heat transfer rates.
