Turbulent flows, Optical metrology and Advanced processing

The aim of this area is to help reduce vehicle fuel consumption and improve energy production systems, which are priorities of the Region’s SRI-SI (Intelligent Specialisation of Research and Innovation Strategy).

As such, it forms part of the ‘Science for a Changing Planet’ Hub of the ULNE I-SITE (Université Lille Nord-Europe) and within the scientific, technological and societal challenges of ‘Clean, safe and efficient energy’ and ‘Green and integrated intelligent transport’.

More specifically, Centrale Lille’s research activities concern the study, modelling and control of turbulent flows using experimental and numerical approaches. The general objective is to understand the physical phenomena of turbulent flows.

These activities also focus on the development of tools and experimental methods, as well as their characterisation, for the study of turbulent flows and the development of methodologies for data control and enrichment. The use of data analysis techniques is currently a major research theme for the reconstruction of 2D or 3D velocity fields from sparse numerical or experimental data, or data that is insufficiently resolved in space or time.

Efforts are currently focused on wall turbulence subjected to an adverse pressure gradient. One of the 5-year objectives in this theme is to take an interest in boundary layer flows strongly perturbed by strong roughness or a boundary layer interacting with a profile (drone or wind turbine). Centrale Lille thus wishes to extend its area of expertise to new problems such as those associated with the aerodynamics of turbulent flows in complex geometries or atmospheric flows.

To carry out these themes, Centrale relies on the LMFL Kampé de Fériet, which stands out in the national landscape for its ability to deal with fundamental questions relating to turbulent flows, making it possible to remove scientific barriers to industrial problems, particularly in the aeronautics and space sectors.
