| Summary: | Pipeline vibration problems are well-known and become significant issues in many fields especially in the oil and gas sectors. The main goal of this work is to analyse the fluid-induced vibration phenomena for large pipelines. Understanding the dynamic characteristics of this kind of span pipelines, which often accommodate axial flow of gas is very important. This work presents modelling and analysis of fluid-induced vibration of pipeline systems made of composite materials. Clamped-clamped pipelines conveying natural gas are investigated. The influence of composite materials layup, the ratio of pipe radius to pipe-wall thickness, liquid density and viscosity, fluid flow velocity, and fluid pressure are all considered. The simulations using Computational fluid dynamics (CFD) and finite element analysis (FEA) are performed using ANSYS software. These simulations show the effects of velocity, pipe geometry, fluid-solid interaction, boundary conditions and fluid properties into the stability of the pipeline. Based on this work, if the vibration frequency of pipe is high does not mean that the amplitude will increase. |
