Mathematical model for coupling a quasi-unidimensional perfect flow

Autor: Msallam, Régis, Dubois, François

Nonlinear acoustics of wind instruments conducts to study unidimensional fluid flows. From physically relevant approximations that are modelized with the thin layer Navier Stokes equations, we propose a coupled model where perfect fluid flow is descr
