Detailed description#

pour un fluide sans modelisation de la turbulence. On suppose l’hypothese de fluide quasi compressible. Sous ces hypotheses, on utilise la forme suivante des equations de Navier_Stokes: DU/dt = div(terme visqueux) - gradP/rho + sources/rho div U = W avec DU/dt : derivee particulaire de la vitesse rho : masse volumique Rq : l’implementation de la classe permet bien sur de negliger certains termes de l’equation (le terme visqueux, le terme convectif, tel ou tel terme source). L’inconnue est le champ de vitesse.
