Strömungsmodellierung anhand maschinelles Lernen
Titel auf Englisch: Flow Modeling with Machine Learning
Lernergebnisse
The students are offered an introduction to machine learning in the context of computational fluid dynamics, and turbulent flow analysis and modeling. Elementary definitions and concepts in machine learning will be motivated by CFD applications. A large part of the course is dedicated to the analysis of numerical simulation data using supervised learning approaches. Some aspects of flow feature extraction using unsupervised learning, reduced order modeling, as well as general State-Of-The-Art research issues in machine learning for CFD will also be discussed. At the end of the course, the students are able to understand the key concepts and algorithms in machine learning and how they could be applied in CFD.

Empfohlene Voraussetzungen
The student should be highly motivated to study numerical simulations of fluid flows using computational methods. This is a Python-based course demanding some relevant programming background. To that extent, successful completion of the module “Introduction to Computational Thinking and Programming for CFD” is highly desired (but not mandatory). Completion of the module “Turbulence Modeling” is also recommended for a better theoretical overview, but not mandatory.
Prüfungsmodalitäten
- Successful completion of the 4-6 exercises discussed in the course
- Oral exam (Presentation of short project with consecutive discussion of the results), 30-45 min.
