Abstract
This training course aims at providing advanced training and formation in the field of turbomachinery flows. To do so, participants will reinforce their theoretical background in fluid dynamics as understood in the context of turbomachinery applications. These specificities will then be particularly developed in the specific context of Large Eddy Simulations whenever devised for the prediction of these flows. In this case, introduction and use of the in-house CERFACS LES code, named Turbo AVBP, will be specifically detailed. To do so, Hands-on sessions are organized to put the theoretical courses into practice.
Objective of the training session
The objective of this training course is to become familiar with LES of turbomachinery flows and more specifically the use of the proposed tool Turbo AVBP.
Learning outcomes
On completion of this course, you will be able to:
- Explain the concept of turbulent scale separation and LES
- Use and constructed test cases around turbomachinery applications with Turbo AVBP,
- Define a-priori parameters for a Turbo AVBP LES computation (mesh genration, CPU cost…)
- Become familiar numeric and modeling of LES for such flows
- Analyze the predictions
Target participants
This training session is for students, engineers, physicists and computer scientists who wish to reinforce or extend their theoretical background to the precise use and analysis of LES simulations. Specific use of Turbo AVBP will also be enforced.
