Purpose This study aims to investigate magnetohydrodynamic (MHD) conjugate pure mixed convection considering interior heat production and resistive heating inside a square closed/open cavity featuring rotating cylinder for aiding (clockwise) opposing (counterclockwise) flow configurations. Moreover, the impacts of altering size conductivity on system’s overall performance determine optimum conditions are examined in this investigation. Design/methodology/approach The closed chamber is differentially heated by keeping high low temperatures at vertical boundaries. In contrast, open has left wall an right boundary. Galerkin finite element method used solve Navier–Stokes thermal energy equations, which construct present study’s mathematical framework. Numerical simulations conducted specified ranges several controlling parameters: Reynolds (31.62 ≤ Re 1000), Grashof (10 3 Gr 10 6 ) Hartmann numbers (0 Ha 31.62), volumetric generation coefficient (Δ = 0, 3). Findings When , simultaneously increase, average Nusselt number along warmed boundary rises accordingly. Conversely, lowers transmission within computational domain, also monitored regarding mean fluid temperature, entropy criterion. Finally, confirms better than cavity.
