Objectives: The aim of this course is to introduce the fundamental steps required to perform two-dimensional, two-component (2D-2C) Particle Image Velocimetry (PIV) for the study of aerodynamic phenomena. The work will focus on understanding the experimental setup, seeding methods, illumination, image acquisition, and calibration processes necessary for accurate velocity field measurement. Emphasis will be placed on the main stages of post-processing, including image pre-treatment, cross-correlation, vector validation, and statistical analysis of flow fields. The course will also cover techniques to extract meaningful flow parameters such as velocity profiles, vorticity, and turbulence characteristics. By the end of the course, participants will gain practical insight into how PIV data can be processed, analyzed, and interpreted to study aerodynamic behavior under various flow conditions.

Courses: 8 hours

• Demonstration and measurement (4 hours)

Experimental setup of a PIV system in a wind tunnel

Calibration and data acquisition procedures

• Post-Processing (4 hours)

Processing of PIV images using MATLAB

Analysis and interpretation of velocity fields

Objectives : Most fluid flows occurring in nature as well as in engineering applications are turbulent. The scope of this course is to introduce some of the basis of the turbulence theory and its statistical analysis. The Emphasis will be put on turbulent flow features that are of primary interest for turbulent flow prediction and modelling. The concepts will be illustrated by a fair set of representative examples issues from both the automotive and aeronautic industry.

Courses : 15h

• Basic concepts (Turbulent Flows, Control Parameters, Some Practical Consequences of Turbulence).
• Statistical Description of turbulent Flows (Reynolds Averaged Navier Stokes equations, Kinetic energy budget).
• Wall-bounded Flows and Free Jets (Boundary Layer, Mixing Layer).
• A glimpse at simulation of turbulent flows (RANS turbulence models, LES, DNS, Hybrid RANS/LES).
