Modèle et simulations numériques de la proparation acoustique non-linéaire dans les conduits
Résumé
We propose a quasi monodimensionnal model for propagation
of nonlinear acoustics waves in pipes including viscothermal
boundary layer effects using an integral method analogous
to those used in aerodynamics. We present some numerical
computations on simple cases and an original one, the
nonlinear propagation effect in a trombone.
