Resumen

A procedure for the study of the flow-induced vibration (FIV) phenomenon of pipes conveying turbulent Newtonian fluid flow is proposed. A numerical model that considers the fluid-structure interaction through the bidirectional coupling between these physical domains is used. The Finite Volume and Finite Element methods, respectively, are used to solve the fluid-dynamic and structural domains. The model considers: (i) periodicity condition for quickly obtaining a fully developed turbulent flow, (ii) WMLES S Omega model for turbulence, (iii) pipe with linear elastic material, and (iv) large displacements theory. The model is implemented in ANSYS 2019 R1 software. Three water flow conditions in a clamped-clamped horizontal PVC pipe with 20.4 mm internal diameter are simulated. The results show the same velocity effects on the amplitude and frequency vibration reported by experimental and analytical studies, validating the proposed procedure.
