Locating real eigenvalues of a spectral problem in fluid-solid type structures
Exploiting minmax characterizations for nonoverdamped nonlinear eigenvalue problems we prove inclusion theorems for a rational spectral problem governing mechanical vibrations of a tube bundle immersed in a fluid. The fluid is assumed to be viscous and incompressible, and its velocity field and pressure satisfy the steady Stokes equations.
