Unsteady Simulations: LES, DES, hybrid LES/RANS and Machine Learning
Course, On-line zoom.us, Sweden, December 2, 2024
Large Eddy Simulations (LES) is suitable for bluff-body flows or flows at low Reynolds numbers. To extend LES to cover industrial flows at high Reynolds numbers, new approaches (hybrid LES-RANS, DES, URANS, SAS, PANS, PITM) must be used. They are all based on a mix of LES and RANS. The course will give an introduction to LES and these new methods. Day 3, an introduction will be given on how to use Machine Learning for improving underlying RANS turbulence models and wall-functions.
