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

Teaching methods

The training is an alternation of theoretical presentations and practical work. A multiple choice question allows the final evaluation. The training room is equipped with computers, the work can be done in sub-groups of two people.

Referent teacher: Laurent Gicquel

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.

Prerequisites

In order to follow this course, you need to:

  • KnowUnix commands.
  • Have basic knowledge of Python.
  • Know numerical flow simulations.
  • Have level B2 of CEFR because the training can take place in French of English depending on the audience.

In order to verify that the prerequisites are satisfied, the following questionnaires must be completed. You need to get at least 75% of correct answers in order to be authorized to follow this training session. If you don’t succeed it, your subscription will not be validated. You only have two chances to complete them.
