Abstract

Abstract

Based on the model experiment, the leakage effects introduced by the leaking hole on the flexible pipeline with a constant internal flow velocity were studied. It is found that the leakage effect can change the critical value, so that the deformation increases linearly with the flow velocity. The leakage effect can also increase the deformation amplitude, and at the same time excite different vibration modes of the pipeline system, causing the vibration responses of multiple frequencies. The research provides a basis for the leakage location in pipelines and an experimental reference for numerical simulation.
