ABSTRACT
The study of magnetohydrodynamics (MHD) flow has received much attention in the past years owing to its applications in MHD generators, plasma studies, nuclear reactor, geothermal energy extractions, purifications of metal from non-metal enclosures, polymer technology and metallurgy. In view of the above, theoretical analysis of the effects of buoyancy force, velocity slip, temperature jump and thermal radiation on entropy generation rate were investigated on electrically conducting couple stress fluid through porous channel and highly porous medium. Semi-analytical techniques of Adomian decomposition and differential transform were employed to solve the boundary value problems derived from the conservation of mass, momentum and energy balance. The velocity profile and temperature profile were used to compute the irreversibility ratio and Bejan number. Graphical representations were presented to explain the effects of various flow parameter variations. From the results, it was found that increase in magnetic field and buoyancy force increased entropy generation while increase in porosity, velocity slip and temperature jump parameters retarded entropy generation rate. Moreover, both irreversibility due to viscous dissipation and heat transfer contributed to entropy generation rate
