Abstract

Abstract: Due to the special working environment of the vertical submarine pipeline, the experimental research is difficult, so this paper makes a numerical simulation study on the turbulence vibration response of the vertical submarine pipeline based on Fluent software. It solves the vibration law of vertical submarine pipeline under different working conditions, and analyzes and discusses the vibration law of the vertical pipeline on the seabed. By establishing the geometric model of the vertical submarine pipeline based on the similarity principle, the flow field distribution law and the vibration law of the vertical submarine pipeline are obtained. When comparing the results of numerical analysis with the experimental results, the selected physical mathematical models are valid, with a margin of error of not more than 10 percent. Therefore, the vibration law and the movement law of the surrounding flow field of the vertical pipeline under different wall thickness, length, incoming flow velocity, different constraints and whether or not to add vibration absorber are analyzed. The results show that the vibration shape of the vertical pipeline is "8" shape under the action of incoming flow.
