The aim of this study is to investigate convective heat transfer on a flat surface in the presence magneto-hydro-dynamic (MHD) flow. analysis considers Darcy-Forchheimer porosity medium focuses analyzing rate, incorporating joule heating and convective-conductive flux effects. influence varying fluid properties flow behavior examined. governing equations are initially expressed as partial differential (PDEs) then transformed into ordinary (ODEs) using appropriate similarity transformations. numerical method RKF-45 employed solve these ODEs. results highlight impact different parameters model. It observed that higher Darcy parameter leads decrease velocity. Additionally, performance carbon nanotubes superior compared MoS2 nanoparticles study.
