The propagation of natural
waves in a cylindrical shell (elastic or viscoelastic) that is in contact with
a viscous liquid is considered. The problem reduces to solving spectral
problems with a complex incoming parameter. The system of ordinary differential
equations is solved numerically, using the method of orthogonal rotation of
Godunov with a combination of the Muller method. The dissipative processes in
the mechanical system are investigated. A mechanical effect is obtained that
describes the intensive flow of mechanical energy.
