AB - This study presents a numerical investigation on the mixed MHD convection of a hybrid Cu-Al2O3-water nanofluid within a driven-wall cubic cavity. An isothermal block at temperature, Th, is positioned on the left wall of the cavity, while the right wall is maintained at a temperature Tc (˂Th). An inclined magnetic field is applied to the entire system. The finite volume method, combined with the SIMPLE algorithm for velocity-pressure coupling, was adopted to solve the governing equations. Parameters such as Reynolds number (50:200), Richardson number (0.01:100), Hartmann number (0:100), magnetic field tilt angle, γ, (0°:90°), and nanoparticle volume fraction, Φ, (0:0.06) were examined. Observations are illustrated through streamlines, isotherms, velocity profiles, and average Nusselt number. The results show that increasing the Reynolds number, Richardson number, and nanoparticle volume fraction, Φ, improves heat transfer within the cavity. Conversely, an increase in the Hartmann number has an unfavorable effect on heat transfer.
