Resumo

A new iterative computational technique for solution of the transient, one-dimensional heat conduction equation, termed the isotherm migration method, is described. The method is shown to have important advantages in problems with temperature dependent properties, phase change, or substantial change in size of the thermally affected region. The principal equation of the method is derived by replacement of the usual dependent variable, T(x,τ), with the isotherm position, x(T,τ) in an energy balance expression. Techniques for starting the method, the treatment of various boundary conditions, stability, truncation error and relative efficiency are discussed.
