Turbulence and particle transport

Educational objectives


Turbulence is a canonical example of multi scale phenomenon. This multi scale character is actually at the very center of the phenomenological theory of turbulence by Kolmogorov.

 

During this lab course, the trainees will be initiated to two measurement techniques used for the spatial mapping of a flow, that will be illustrated through the study of the wake development behind a cylinder, a classical study case of turbulence.

 

This introduction to major experimental techniques in fluid mechanics (and to their limitations) will be augmented by an initiation to numerical techniques (and the issues associated to them) such as direct numerical simulations, RANS method, or Large Eddy Simulations.
