Abstract

Onset of internally heated convection in a porous medium saturated couple-stress fluid with the effect of throughflow and magnetic field is investigated. The governing nondimension
equations are solved using the normal modes, which leads to an eigenvalue problem for the linear stability analysis. The eigenvalue problem is solved by bvp4c in MATLAB R2020a. The critical values of the Rayleigh number are obtained for different prescribed values of the other physical parameters.
