Abstract
The present article investigates the effect of flow and heat transfer characteristics of a thin
layer of third grade fluid that is flowing steadily over a heated incline plate. The mathematical
formulations for the physical system are based on the combination of momentum together with heat
conservation laws that forms the theoretical framework for the present investigation. The exact
solutions of the dimensionless nonlinear problems are obtained and valid for both small and large
parameter values. The effects of viscous dissipation and heat transfer are balanced in the energy
equation and play a major role in the entropy generation procedure. The result of the mathematical
analysis revealed the significance of thermal effects together with the entropy built-up due to
incomplete energy conversion.
