This study aims to investigate the effect of a constant magnetic field on heat transfer, flow fluid, and entropy generation mixed convection in lid-driven porous medium enclosure filled with nanofluids (TiO2-water). Uniform fluxes are partially applied bottom wall enclosure, while remaining parts considered be adiabatic. The vertical walls maintained at cold temperature move fixed velocity. A sinusoidal is assumed kept adiabatic top enclosure. Three scenarios corresponding different directions moving isothermal (±1). influence pertinent parameters an deliberated. Richardson number (R~i = 1, 10, 100), Hartmann (0 ≤ H~a 75 25 step), solid volume fraction nanoparticles Φ~ 0.15 0.05 step). Grashof Darcy numbers 104 10−3, respectively. finite element method, utilizing variational formulation/weak form, discretize main governor equations. Triangular elements have been employed within studied envelope, adapting as needed. results showed that streamfunction fluid decreased increased. local N~u increased by more than 50% low values (up 0.1). percentage decreases between 25% 40% when range 0.1 0.15. As increases from 0 75, these percentages increase value R~i=1 10. These variations primarily dependent number.
