"Viscous damping issues in the dimension reduction of a fluid conveying tube";
Proceedings of the Institution of Mechanical Engineers Part C - Journal of Mechanical Engineering Science, 225 (2011), 10; 2347 - 2353.



English abstract:
We consider the dimension reduction of an already discretized model for a fluid-conveying tube by the linear and non-linear Galerkin method. We show, how the viscous damping parameter affects the distribution of the eigenvalues for the system and how this distribution influences the convergence of the approximation. By a simple mechanical model, it is also demonstrated that the Galerkin method may fail completely, if the energy dissipation is governed by the stable modes.

Keywords:
dimension reduction; non-linear Galerkin method; Viscous damping; energy dissipation
