Wire coating analysis by withdrawal from a bath of Sisko fluid

In this paper, the wire coating analysis by withdrawal from a bath of Sisko fluid is investigated. The relevant equations are first modelled and then solved by utilizing the homotopy analysis method ( HAM). The convergence of the obtained series solution is carefully analyzed. The influence of the non-Newtonian parameter on the velocity, volume flow rate, radius of coated wire, shear stress at the surface of the wire and the force required to pull the wire is seen and discussed.
