Abstract

An investigation of an electrically conducting viscous fluid within an annulus incorporating the influence of a radial magnetic field using the Rosseland diffusion approximation with porous material has been caried out. Both steady and unsteady solutions are obtained by applying regular perturbation and implicit finite difference methods. The key findings of this research shows that suction decreases temperature and velocity, while injection increases them. Magnetic fields reduce velocity, whereas higher Darcy number, Grashof, and radiation parameters enhances it especially under isothermal conditions.
