The numerical analysis examines the attributes of magnetohydrodynamic natural convection in a closed cavity including circular hollow. Because mono and hybrid nanofluids have many applications thermal engineering manufacturing, are utilized as substance within entire domain. investigation centers on closed, trapezoidal-shaped hollow with heated surface ring. inclined vertical walls treated cold exteriors, while others insulated. Another factor is taking magnetic field horizontally to cavity. contains nanofluid, an amalgamation SiO 2 Ag nanoparticles water. associated governing equations simulated via finite element method. Exploiting streamlines, isotherms, line graphs, results physically explained for range values Rayleigh number (103 ≤ Ra 106), nanoparticle volume fraction (0 ϕ 0.1), Hartmann Ha 100). RSM used display 2D 3D effects significant factors response function. A best-fitted correlation built up examine rate sensitivity. It found that incorporating intensifying directs actuation nanofluid. In event growing impact, reverse behaviors should be noted. water's ability transmit heat increases 11.29 % when Ag-SiO -H O nanofluid used. imposition (Ha = 25), transmission lessens 2.4 %. has positive sensitivity whereas shows inverse behavior. Lastly, study's findings might guide designing successful convective mechanical device.
