Flow-induced vibration (FIV) in piping system presents a major durability and ultimately containment challenge in production and process facilities. This webinar will begin with a concise introduction to FIV and examine three commonly encountered FIV mechanisms; turbulence-induced vibration, multiphase flow induced vibration and acoustic induced vibration.
Screening tools for identifying FIV related risks, such as the Energy Institute AVIFF guidelines, will be discussed as a good initial assessment approach. The limits of these guidelines for some mechanisms will be explored. Where a high risk is identified by these screening methods, simulation-driven approaches can be used to predict the associated excitation forcing and resulting vibration response of the system. Using some relevant case studies and benchmarks, we will demonstrate how CFD, Acoustic FEA and Structural FEA simulations can deliver valuable insights that inform the re-design or modification of these piping systems to enhance their durability.
The talk will aim to give engineers involved in the design and operation of process piping systems a good overview of the range of engineering approaches to FIV risk management and the value that numerical simulation can add to this process.
