Abstract

A mathematical model for third grade fluid is developed for the wire coating, using a conical unit, where the flow is dependent on the wire velocity and the geometry of the unit. The nonlinear constitutive equations are formulated in cylindrical coordinates and theoretical results are obtained by using the homotopy perturbation method. Explicit analytical expressions for velocity field, radius of the coated wire, volumetric flow rate, shear stress on the wire surface and force on the total wire surface have been derived.
