Output-based discretization error control in turbulent flow simulations

Krzysztof J. Fidkowski is a Professor of Aerospace Engineering at the University of Michigan.  He earned his S.B. in Physics and S.B., S.M, and Ph.D. degrees in Aeronautics and Astronautics from MIT.  His doctoral thesis was in computational fluid dynamics and investigated the applicability of high-order discontinuous finite-element methods to aerodynamics simulations over complex geometries.  Before joining the University of Michigan in 2008 as an assistant professor, he was a post-doctoral associate at the Aerospace Computational Design Laboratory at MIT, where he worked on projection-based reduced models.  At the University of Michigan, Professor Fidkowski teaches aerodynamics, numerical methods, and computational fluid dynamics. He has received young investigator awards from the Department of Energy and the Air Force Office of Scientific Research.  He previously served as chair of the CFD Subcommittee of the AIAA Fluid Dynamics Technical Committee, organized fluids and CFD tracks at multiple AIAA conferences, and is an AIAA Associate Fellow.  His primary research field is in algorithmic development for computational fluid dynamics, specifically in the use of adjoint methods for numerical error estimation, mesh adaptation, and uncertainty quantification.  In recent work, Professor Fidkowski has studied reduced models of high-order dynamical systems, optimization under uncertainty, machine learning for error estimation and mesh adaptation, panel methods for low-speed aerodynamics, and dynamic closure models for turbulent flows.

The role of experiments and data reduction techniques in the tuning of different transition models

Abstract

Prof. Daniele Simoni is the Head of the Aerodynamics and Turbomachinery Laboratory of the University of Genova. He graduated in Mechanical Engineering at the University of Genova with honours (09/2005). He received his PhD in Fluid Machinery from the University of Genova in 2009. He became Full Professor at the University of Genova in 2020. Since 2023 he is Coordinator of the Ph. D course in “Machine and Systems Engineering for Energy, Environment and Transport”. Prof. Daniele Simoni developed expertise in the design of open and closed loop wind tunnels, and in the design of turbomachinery and aeroengine components. He is expert on the application and data analysis of advanced measuring techniques for the investigation of time-dependent unsteady and distorted flow fields developing into turbomachinery components, such as laser Doppler Velocimetry, Time Resolved Particle Image Velocimetry, Fast Response Aerodynamics Pressure Probes (FRAPP), as well as hot-wire and hot-film anemometers.
