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 to estimate the lifetime of the different components (pipelines, heat exchangers, turbines etc.) with regard to fatigue, stress corrosion cracking, possible failure modes and mechanical wear. Recently, the use of numerical tools to simulate FIV has received large interest due to the availability of more computational resources and the necessity to analyse 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 the framework of this lectures series, several well-known experts from around the world will give lectures on the important topics related to the computational FSI in order to understand and study the FIV in different industrial applications. This lecture series aims 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.

All the participants (students, postdocs, young researchers,…) are invited to prepare a 5 minutes pitch presentation of their research. This presentation will allow the participants to further interact with the lecturers. The three best pitches will be awarded with a certificate and a prize.

The Lecture Series co-directors are Dr. Afaque Shams from NRG (The Netherlands) and Mr. Philippe Planquart from the von Karman Institute (Belgium).
