Modèle et simulations numériques de la proparation acoustique non-linéaire dans les conduits

cote interne IRCAM: Msallam97a/International audienceWe 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, thenonlinear propagation effect in a trombone
