Numerical simulation of slip influence on the flow of a MHD Williamson fluid over a vertical convective surface

Abstract

An analysis of this paper is examined, two-dimensional, laminar with heat transfer on natural convective flow in an electro-conductive polymer on the external surface of a vertical plate under radial magnetic field and slip effects is considered. The coupled governing partial differential equations are transformed to ordinary differential equations by using non-similarity transformations. The obtained ordinary differential equations are solved numerically by a well-known method named as Keller Box Method (KBM). The computed results for the velocity and temperature profiles as well as heat transfer and skin-friction coefficient have been depicted and discussed in detail through graphs for various parametric conditions. Increasing thermal slip strongly decreases skin friction and Nusselt number. Skin friction is also depressed with increasing magnetic body force parameter. Increasing momentum slip is observed to decrease skin friction. The model is relevant to the simulation of magnetic polymer materials processing.
