/**
 * Cette classe permet d'imposer une loi de paroi de type nombre de Nusselt imposee.
 * La fonction de Nusselt rentree par l'utilisateur peut etre une fonction de l'espace, du nombre de Reynolds
 * et du nombre de Prandtl.
 * Ces nombres de Reynolds et de Prandtl sont evalues a partir des quantites en paroi (vitesse, temperature etc...). Il convient donc de tenir compte de cela dans l'entree de la correlation du Nusselt.
 * En effet, souvent les correlations de Nusselt utilise la vitesse moyenne dans la conduite.
 * C'est pourquoi cette loi de paroi s'appliquera souvent dans le cas ou le probleme fluide ets resolu
 * avec une seulle maille afin que la vitesse calcule represente exactement par conservation du debit la vitesse moyenne de l'ecoulement.
 * Syntaxe :
 * Loi_Paroi_Nu_Impose { nusselt fontion_de_(x,y,z,Re,Pr)
 diam_hydr valeur_diametre_hydraulique
