报告摘要1：
Bluff body flows are ubiquitous in science and engineering. Suspended bridges, tall buildings, chimneys are just a few examples of bluff bodies whose interaction with wind has to be fully mastered to design safe, long-lasting buildings. The typical behaviour of flows past bluff bodies lies in their unsteadiness, with the development of strong vortex wakes. The primary instabilities in the laminar flow past bluff bodies occur for low Reynolds numbers, in the order of magnitude of 50. Nevertheless, even for high Reynolds numbers, in the turbulent regime, these flows are reminiscent of the primary instabilities from a qualitative viewpoint. For this reason, investigating the primary instabilities is key to unveil the physics behind the flow past bluff bodies. In this seminar, I will review the research carried out at the Department of Aerospace Science and Technology in the last decade to investigate the stability of the flows past bluff bodies and to control them.
报告摘要2：
As the computing power available for CFD simulations is rapidly increasing, there is an increased interest in the development of new algorithms capable of fully taking advantage of the new massively parallel architectures. In this talk, I will present solvers developed to investigate incompressible flows in complex geometries. Two solvers will presented, both based on the direction-splitting fractional step method recently proposed by J.-L. Guermond & P. Minev. The first one leverages a staggered-grid arrangement and can deal with arbitrarily complex geometries by an MLS treatment of immersed boundaries. The second one exploits a co-located coupling between velocity and pressure, leading to an extremely fast solver. Test cases and advanced applications showing the accuracy and performance of both methods will be presented.

Prof. Franco Auteri currently serves as a Full Professor of Fluid Dynamics at the Department of Aerospace Science and Technology, Politecnico di Milano (Polimi), Italy. With a distinguished academic and research career spanning over two decades, he has emerged as a leading expert in fluid dynamics and related domains. He obtained his Master's degree in 1995 and PhD in 2000, both from Polimi, with his doctoral thesis titled A hierarchical triangular spectral element method for incompressible fluid dynamics simulation. Since 2021, he has also been leading the Programming quantum computers with Qiskit course offered by IBM-CRUI. His research interests span a broad range of topics in fluid dynamics and aerospace engineering, including: (1) CFD and spectral methods for fluid simulation; (2) Flow stability, transition, and turbulence; (3) High-performance computing and quantum computing applications in fluid mechanics; (4) Fluid-structure interaction and experimental aerodynamics.
His international academic experience includes several prestigious visiting appointments: (1) Visiting researcher at Ladhyx Lab, Ecole Polytechnique Paris (France, 2011, host: P.J. Schmid); (2) Visiting professor at Beihang University (Beijing, China, 2019), where he taught aerodynamics; (3) Visiting researcher at Texas A&M University (USA, 2018) and Institut de Mécanique des Fluides de Toulouse (France, 2023).
Prof. Auteri's research has generated substantial academic output, including 3 authored or edited books and over 40 refereed international journal papers published in top-tier journals such as Journal of Fluid Mechanics, Journal of Computational Physics, Physics of Fluids, and Aerospace Science and Technology. His work covers key areas of fluid dynamics, including flow stability, turbulence, computational fluid dynamics (CFD), and high-performance computing.
He has led numerous high-impact research projects, particularly in the field of sustainable aerospace engineering and computational fluid dynamics. Notable ones include: (1) Principal Investigator (PI) for Politecnico di Milano in the MSCA-DN project Towards sustainable Computational Fluid Dynamics (FairCFD) (2025–2029), with total funding exceeding 4.5 million euros; (2) PI and leader of Work Package 5 (Experimental evaluation) in the Horizon Europe Pathfinder Open project Bioinspired Electroactive Aeronautical multiscale LIVE-skin (BEALIVE) (2023–2026); (3) PI for Politecnico di Milano and leader of WP 5 (Aerodynamic evaluation) in the H2020 project Smart Morphing and Sensing (SMS) (2017–2020), with total funding of over 3 million euros.
Prof. Auteri is actively engaged in academic service and scientific organization, while holding key administrative roles at Polimi: Member of the Departmental Council (2022–present), Member of the Departmental Scientific Committee (2020–present), and Scientific Director of the Department’s Computing Laboratory (2021–present).
