Waves in thin-walled fluid-filled ducts with arbitrary cross-sections
2008 (English)In: Journal of Sound and Vibration, ISSN 0022-460X, E-ISSN 1095-8568, Vol. 310, no 1-2, 58-76 p.Article in journal (Refereed) Published
First, a variational formulation for fluid-shell coupling is presented. Subsequently new waveguide finite elements for fluid and fluid-shell coupling are derived from this formulation. Together with previously derived elements, modelling thin-walled shells, equations for pipes and ducts with arbitrary cross-sections may be formulated. Two examples, one pipe and one duct, are presented together with dispersion curves for the respective case.
