Abstract
This paper investigates the effect of couple stresses on the entropy generation rate of
an incompressible viscous fluid through a porous channel with convective heating at the walls. Semi analytical solutions of the dimensionless momentum and energy equations are obtained using the
rapidly convergent modified Adomian decomposition method. The approximate solutions are used to
compute the entropy generation numbers, irreversibility distribution ratio and the Bejan number in the
flow field. The effects of various flow parameters on the velocity and temperature are discussed and
shown graphically
