Fluid-structure interaction in free vibration analysis of pipelines
Journal Title: Вісник Тернопільського національного технічного університету - Year 2016, Vol 81, Issue 1
Abstract
We analyze the impact of the transported fluid on the natural frequencies of a pipeline. Solution of coupled acousto-mechanical problem for straight pipe is given by the Transfer Matrix Method. The equations for junction coupling are given. Several practical examples demonstrate the importance of taking into account the fluid-structure interaction. It is shown that treating fluid as an added mass at the axial vibrations can lead to significant errors.
