Fluid-Structure Interaction for Nuclear Applications

image de Fluid-Structure Interaction for Nuclear Applications

Flow-induced vibration (FIV) is a phenomenon resulting from the interaction of flexible structures immersed in highly energized fluid flows, and it falls in a more general category of fluid-structure interaction (FSI) problems. FIV plays an important role in many industrial applications. The knowledge and understanding of FSI/FIV are critical for estimating the lifetime of the different components (pipelines, heat exchangers, turbines etc.) concerning fatigue, stress corrosion cracking, possible failure modes, and mechanical wear.

Experimental techniques are traditionally applied to study FIV. By measuring the flow field and the response of the structure at the same time allows us to correlate the flow features and the vibration, helping to mitigate the problem. Recently, the use of numerical tools complementing experimental studies to simulate FIV has received large interest due to the availability of more computational resources and the necessity to analyze complex configurations with more details. These approaches are based on the use of Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSM) tools, which are coupled together to solve FSI problems.

In this Lecture Series, aimed at providing a detailed background to welcome novices in the field as well as a comprehensive overview of recent developments of computational FSI in various industrial applications, several well-known experts from around the world will present the theoretical frame of FIV, and of the state of the art in experimental and numerical techniques in single-phase and multiphase flows, demonstrating them through bundles in parallel and crossflows.

This Lecture Series has been organized in the context of the GO-VIKING project, which has received funding from the European Union’s Euratom research and innovation programme under grant agreement No 101059603.

Programme and registrations coming soon.
