UNSTEADY FLOW AND HEAT TRANSFER OF JEFFREY FLUID OVER A STRETCHING SHEET

Abstract

The boundary layer flow and heat transfer of an incompressible Jeffrey fluid have been nvestigated. The analytic solutions of the arising differential system have been computed by homotopy nalysis method (HAM). The dimensionless expressions for wall shear stress and surface heat transfer re also derived. Exact solutions of the momentum equation and numerical solutions of the dimensionless nergy equations have been obtained for the steady-state case. The results indicate an increase in the elocity and the boundary layer thickness by increasing the elastic parameter (Deborah number) for a effrey fluid.
