Abstract

On présente dans cet article une méthode de simulation des champs thermiques stationnaires dont la conductivité est fonction de la température et où il y a dégagement interne de chaleur. Cette méthode basée sur une double transformation permet de débarrasser le champ des nonlinéari tés et des sources internes en introduisant les modifications des conditions aux limites. Ceci permet, pour résoudre le problème par l'analogie rhéoélectrique d'opérer avec un système de dispositifs électroniques simples sur un milieu continu et homogène. Quatre exemples ont été traités et comparés avec la solution numérique. La précision de la méthode est très satisfaisante. La simplicité de la méthode, la continuité du milieu, le faible prix des dispositifs électroniques valorisent les méthodes d'analogie rhéoélectrique pour les études de champs thermiques.
