Model of thermoviscous acoustic propagation in thin rough tubes
Contributors: Alexis Thibault (Ph. D. student), Henri Boutin (STMS UMR 9912), Juliette Chabassier, Thomas Hélie (STMS UMR 9912) Thermoviscous acoustic propagation in a tube with corrugated isothermal rigid walls is considered. At long wavelengths, it amounts to a 1D transmission line equation, in which the coefficients depend on the solution…
