Abstract: Understanding the transition of fluid flows has been and still is a crucial focus in fluid dynamics. Stability theory has greatly helped on this side and has opened the door to other branches in fluid dynamics, such as flow control. By leveraging insights on flow transition, flow control technology can help mitigate the human impact of environmental and noise pollution caused by fluid-based systems such as aircraft, automobiles, and wind turbines, all while improving their overall performance.

From linear stability analysis to resolvent analysis, this talk will cover some of the methods that enable such investigations and the limitations, in terms of computational resources, on applying them to turbulent flows.

About Speaker: Dr. Rolandi obtained a BSc in Mathematical Engineering from Politecnico di Torino and an MSc in Computational Science and Engineering from Politecnico di Milano. She later completed a Ph.D. in Fluid Dynamics at the Institute Supérieure de l’Aéronautique et de l’Espace (ISAE-Supaero) before joining the Mechanical and Aerospace department at UCLA as a postdoctoral researcher at Professor Taira’s Lab. Her research at UCLA focuses on developing and implementing algorithms helpful in characterizing, modeling, and controlling turbulent flows.
