Abstract
In this work, an analytical study of inherent irreversibility in the thin film flow of a
viscous incompressible couple stress fluid down an inclined heated channel with adiabatic free surface is investigated. It is assumed that the fluid viscosity varies exponentially with temperature. Analytical
expressions for fluid velocity and temperature are derived and used to compute entropy generation
rate, irreversibility distribution ratio in the flow field and results are presented graphically and discussed.
