Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 20 Maggio nell’aula Fassò (Edificio 4A), dalle 17:15 alle 18:30 CET.

PhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento.

Lo speaker Daniele Di Cristofaro condurrà un seminario dal titolo “Numerical Methods for Fluid-Structure Interaction Problems Involving Lightweight Structures”. 

Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.

Sarà possibile seguire la conferenza anche online al seguente 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.
