Solution of heat transmission equation including the phase change through computerised electrical analogy.

Author(s) : DOMÍNGUEZ M., ARIAS J. M., GARCÍA C., et al.

Summary

A new simulation technique, based on computer assisted solution of the electrical analogy, is developed for the study of thermal problems, including the phase change. In this method the capacitor is substituted by equivalent resistors, which value is a function of the increase in the calculation time and of the capacity. The problem is reduced to the solution of the equation for the grids and nodes, the number of elements in the grid is fixed and the thickness is varied at each iteration. The results obtained in some cases of simulation are indicated and for some examples analytical solutions are compared. The conclusion is that the new method is suitable for performing these studies.
