Phase shift effects for fluid conveying pipes with non-ideal supports

Research output: Chapter in Book/Report/Conference proceeding › Article in proceedings › Research › peer-review

Abstract

Vibrations of a fluid-conveying pipe with non-ideal supports are investigated with respect to phase shift effects. A numerical Galerkin approach is developed for this general problem, and the use of it exemplified with a investigation of phase shift effects from rotational damping at supports of a simply supported pipe. It is found that asymmetric viscous rotational damping at supports gives rise to phase shifts along the pipe which cannot be distinguished from phase shift from mass flow. This is of interest, e.g., for the development and troubleshooting of Coriolis flow meters.
