Durability quantification through advanced analysis

09 February 2021

Assessing durability of systems affected by flow-induced vibration is complex. In this webinar we show how Norton Straw has developed approaches combining flow and structural simulation to aid production and process system operation.

Flow-induced vibration (FIV) presents a major durability and integrity challenge in many engineering systems and facilities. In this webinar we provide a concise introduction to the challenge and examine three commonly encountered fluid-induced vibration mechanisms; turbulence-induced vibration, multiphase flow-induced vibration and acoustic-induced vibration.

Screening tools suitable for identifying flow-induced vibration risks, such as the Energy Institute guidelines for vibration avoidance, are discussed as a good initial assessment approach. The limits of these guidelines for some mechanisms are then explored.

Where a high risk is identified by screening methods, simulation-driven approaches can be used to predict the associated excitation forcing, resulting vibration response of the system and ultimately the durability can be quantified.

Using some relevant case studies and benchmarks, this webinar demonstrates how simulation techniques like Computational Fluid Dynamics (CFD), Acoustic and Structural Finite Element Analysis, an deliver valuable insights that inform the re-design or modification of systems to enhance their durability.

This webinar aims to give engineers, involved in the design and operation of process piping systems, a good overview of the range of engineering approaches to flow-induced vibration risk management and the value that numerical simulation can add to this complex operational challenge.
