The next event in the PhDTalks series will take place on Tuesday, May 20th in the Fassò room (Building 4A), from 5:15 PM to 6:30 PM CET.

PhDTalks is a series of seminars and discussions among PhD students. The events aim to provide a space for networking among PhD students and connecting with the many projects developed within our department.

The speaker, Daniele Di Cristofaro, will lead a seminar entitled: “Numerical Methods for Fluid-Structure Interaction Problems Involving Lightweight Structures”.

At the end of the event, a small refreshment will be available, funded by the department.

It will also be possible to attend the conference online at the following link.

Abstract

Proper modelling of Fluid-Structure Interaction (FSI) phenomena involving lightweight, deformable structures is essential for understanding the complex dynamics in various engineering applications. In this context, the Arbitrary Lagrangian-Eulerian (ALE) Navier-Stokes equations are widely used to track the fluid-structure interface properly. However, mesh distortion remains a significant challenge, particularly when large deformations occur. This distortion can result in poor resolution of the fluid-structure interface, which negatively impacts the accuracy of aerodynamic force predictions and structural responses. This research introduces a novel mesh manipulation algorithm designed to reduce mesh distortion, thereby enhancing the accuracy of FSI simulations. The method is validated through several benchmark cases and applied to real-world problems, including dragonfly flight, sail deformation and hydrofoil, demonstrating its robustness and effectiveness.
