Two-Phase Flow in Wire Coating with Heat Transfer Analysis of an Elastic-Viscous Fluid

Abstract EN

This work considers two-phase flow of an elastic-viscous fluid for double-layer coating of wire.

The wet-on-wet (WOW) coating process is used in this study.

The analytical solution of the theoretical model is obtained by Optimal Homotopy Asymptotic Method (OHAM).

The expression for the velocity field and temperature distribution for both layers is obtained.

The convergence of the obtained series solution is established.

The analytical results are verified by Adomian Decomposition Method (ADM).

The obtained velocity field is compared with the existing exact solution of the same flow problem of second-grade fluid and with analytical solution of a third-grade fluid.

Also, emerging parameters on the solutions are discussed and appropriate conclusions are drawn.
