Computational Fluid Dynamics (CFD) is a fundamental tool, but traditional numerical methods can introduce artificial errors that alter important physical properties of the system. Structure-preserving CFD offers an alternative approach: designing schemes that respect, at the discrete level, the fundamental properties of the continuous governing equations.
The seminar will present the basic principles of discrete conservation methods and their role in simulating incompressible and compressible flows. It will discuss how to preserve key quantities such as energy, helicity, entropy, and pressure equilibrium, both in space and time, through physics-compatible schemes and adaptive time integration techniques.
Practical examples and implementations in open-source codes will also be presented, highlighting the advantages of these approaches in scale-resolving simulations, where accurately capturing the multiscale nature of the flow without introducing numerical artifacts is crucial. This perspective paves the way for more accurate, stable, and predictive simulations, with important implications for engineering and applied sciences.

Speaker
Francesco Capuano, Assistant Professor Universitat Politècnica de Catalunya, Department of Fluid Mechanics
He earned his Master’s degree in Aerospace Engineering from the University of Naples “Federico II” in 2011, where he also completed his PhD in 2015. He carried out postdoctoral research at the University of Naples (2015–2020) and the Polytechnic University of Bari (2021); he was also a visiting researcher at Stanford University (2014) and a postdoctoral research associate at George Washington University (2017–2018). His scientific work focuses on the development of robust, high-fidelity computational methods for the modeling and analysis of multiscale and multiphysics phenomena in engineering and biological systems. His current research interests include advanced physics-compatible numerical methods for the Navier–Stokes equations, in silico and in vivo analyses of cardiovascular flows, microplastic aggregation in the oceans, and biofilm formation under turbulent flow conditions.
