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.

Prerequisites

In order to follow this course, you need to:

  • Knowledge of Unix commands.
  • Basic knowledge of Python.
  • Knowledge of numerical flow simulations.

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.

Young PhD day

Brigitte Yzel |  19 February 2020

Cerfacs organizes its 5th edition of the Cerfacs Doctoral Students Day on Monday, May 11, 2020. This day will be an opportunity for each doctoral student to present his or her research subject in front of an audience of Cerfacs researchers but also representatives of our industrial and academic partners, as well as selected external guests. Great novelty this year, 10 students have the privilege to participate in a specific training course such as "My thesis in 180 seconds", in order to present their research topic in French and in simple terms. The day will end with the selection of the : best poster, and the best MT180 presentation.Read more
