Application of the Variational Iteration Method for Determining the Temperature in the Heterogeneous Casting-Mould System

In this paper an application of the variational iteration method for determining the temperature in the heterogeneous casting-mould system is presented. Considered problem is modeled by means of the system of two heat conduction equations – for the casting and for the mould, on the contact surface of which the boundary condition of the fourth kind with non-zero thermal resistance is defined. An example illustrating the discussed application and confirming usefulness of this method in solving such kind of problems is also presented. Copyright © 2012 Praise Worthy Prize S.r.l.
