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.
