ABSTRACT In the present paper, we study effect of nonlinear thermal radiation on magnetohydrodynamic (MHD) flow through a porous medium subject to convective boundary condition over permeable vertical plate. The Boussinesq approximation is used predict density variation with temperature (NDT), which enhances transport. Similarity transformations facilitate conversion governing partial differential equations into ordinary equations, enabling further analysis. solutions are obtained and presented graphically using bvp4c method in MATLAB. primary objective our analyze effects suction/injection, NDT, MHD dynamics distribution. conclusions reveal that parameter Grashof number enhance buoyancy forces, increasing velocity layer thickness improving heat dissipation. Higher raises fluid temperature, reduces viscosity, thickens both layers. Suction stability by thinning layers facilitating efficient transfer, whereas strong injection increases thickness, retains heat, disrupts stability. A higher magnetic slows more suction injection. greater Prandtl Nusselt number, while transfer skin friction suction. We have compared numerical results those previous studies observed an excellent agreement. novelty this lies its unique approach modeling radiation, impact media. findings practical implications for various engineering fields, including energy systems, aerospace, biomedical engineering, chemical processing, environmental contributing optimization technological applications.
