/*! @brief Classe Modele_turbulence_hyd_base Cette classe sert de base a la hierarchie des classes
 *
 *     qui representent un modele de turbulence pour les
 *     equations de Navier-Stokes. Il existe deja deux classes derivees
 *     qui representent le modele de turbulence (k,e) et le modele
 *     de turbulence sous maille. Ces deux modeles ont en commun
 *     le calcul d'une viscosite turbulente.
 *
 *     B.Mat. : la classe herite de support_champ_masse_volumique.
 *      en Front-Tracking (et plus tard en qc), elle fournit le
 *      mecanisme pour recuperer rho.
