This study explores the influence of Fe3O4 – Water nanofluid, magnetic forces, and double-diffusive mixed convection characteristics on a steady-state, two-dimensional, laminar flow within an inclined square cavity containing four heated blockages. The governing equations are solved using Finite Volume Method (FVM). In this configuration, temperature concentration inside blockages higher than those left right walls, which moving in opposite directions to each other. remaining two adiabatic impermeable. A wide range parameters is investigated, including nanoparticle volume fractions (φ = 0.0, 0.02, 0.04, 0.06), inclination angle (γ 0°, 30°, 60°), Richardson number (Ri 0.1, 1.0, 10), Hartmann (Ha 0, 50, 100), block ratio (B 1/8), Lewis (Le 5.0), Prandtl (Pr 0.71), Buoyancy (N 2.0). extensively analyzes temperature, concentration, streamline contours based these parameters. Furthermore, research examines heat mass transfer rates surfaces by analyzing local average Nusselt (Nuavg) Sherwood numbers (Shavg). results suggest that introducing nanofluid has more pronounced fields patterns. Both have significant impact both At Ri, increase φ reduces Nuavg Shavg. However, total Shavg decrease at any Ri γ field.
