Abstract

This training course enables the participants to reinforce their theoretical knowledge in order to understand and analyze high fidelity compressible Large Eddy Simulation (LES). Numerical methods, boundary conditions, signal processing and unsteady turbulence modeling are the main subjects tackled. Hands-on sessions are organized to put the theoretical courses into practice.

Objective of the training

The objective of this training course is to become familiar with the LES in order to realize and analyze LES of turbulent flows.

Learning outcomes

On completion of this course, you will be able to:

  • Explain the concept of turbulent scale separation
  • Derived LES equations,
  • Choose a subgrid scale model
  • Define a-priori parameters for a LES (mesh, CPU cost…)
  • Become familiar with compressible boundary conditions
  • Analyze a turbulent flow

Teaching method

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.

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 CFD simulations.

Prerequisites

In order to follow this course, you need to have:

  • Knowledge of Unix commands.
  • Basic knowledge of Python.
  • Knowledge of numerical flow simulations.
  • Level B2 of CERF (the training can take place in French or English depending on the audience).

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.

Questionnaire 1 : Unix commands

Questionnaire 2 : Python edition

Questionnaire 3 : Numerical flow simulations
