Flow-induced vibration (FIV) from high-velocity multiphase flow is a common source of vibration concern in process piping, potentially leading to fatigue failures and hydrocarbon leaks. FIV screening methods tend to be conservative for multiphase flows and are typically only validated for simple single bends at low pressure. In this webinar, Xodus will demonstrate how Simcenter can be used for both Finite Element Analysis (FEA) to predict the response of a system and Computational Fluid Dynamics (CFD) analysis to predict realistic forcing functions in complex combinations of bends and tees typically seen in process piping systems.
Xodus will present a selection of recent case studies where CFD analysis of multiphase flow was performed to predict the forces on pipe bends, including validation against experimental data. In addition, examples of Fluid-Structure Interaction (FSI) will be presented where the CFD solver has been coupled with the Finite Element solver to predict the response of piping to the forces generated by the multiphase fluids. This combination offers a potentially powerful tool for assessing and diagnosing multiphase FIV problems in hydrocarbon production piping systems.
