Boundary Layer Flow and Heat Transfer over an Exponentially Stretching/Shrinking Permeable Sheet with Viscous Dissipation

In this paper, the steady two-dimensional flow of an incompressible viscous fluid over an exponentially stretching/shrinking permeable sheet with viscous dissipation is studied. The governing partial differential equations are transformed into a system of ordinary differential equations and solved numerically by a finite-difference Keller-box method. The flow features and heat transfer characteristics for various values of the governing parameters are analyzed and discussed. Dual solutions are found for the shrinking boundary, while the solution is unique for the stretching boundary.
