Numerical analysis of the intrinsic irreversibility of a mixed convection hydromagnetic flow of an electrically
conducting couple stress fluid through upright channel filled with a saturated porous medium
and radiative heat transfer was carried out. The thermodynamics first and second laws were employed
to examine the problem. We obtained the dimensionless nonlinear differential equations and solves
numerically with shooting procedure joined with a fourth order Runge-Kutta-Fehlberg integration
scheme. The temperature and velocity obtained, used to analyse the entropy generation rate together
with some various physical parameters of the flow. Our results are presented graphically and talk over.
