Heat Transfer in a Non-Newtonian Jeffrey's Fluid over a Non-Isothermal Wedge

Abstract The boundary layer flow and heat transfer of an incompressible Jeffrey's viscoelastic fluid from a non-isothermal wedge is analysed. The surface of the wedge is maintained at a constant temperature. The boundary layer conservation equations, which are parabolic in nature, are normalized into non-similar form and then solved numerically with the well-tested, efficient, implicit, stable Keller-box finite-difference scheme. The variation of the reduced Nusselt and Local Skin Friction numbers with Deborah number, De , for various values of ratio of relaxation to retardation times ( λ ) are also tabulated and provided in graphical form. It is found that the velocity is enhanced with increasing Deborah number whereas temperature is reduced. Increasing λ accelerates the velocity but decelerates the temperature. Increasing the pressure gradient parameter m , velocity increases throughout the boundary layer but temperature decreases.
