Abstract
This paper sets out to investigate parameters that determine flow-induced vibrations in flexible, corrugated pipes. A central element in this paper is a mathematical model that describes the phenomenon. The presented model is designed to capture the aero-acoustic wave behaviour of gas that flows in a corrugated pipe, exploring the feedback analysis. This model involves the coupling between the large-scale acoustic behaviour in a pipe and a line of self-excited oscillators representing vortex excitation caused by flow over corrugations.
