Teaching at Centrale Lyon (3 years cursus/ L3, M1-M2; Masters’ Degree in Engineering)


Former course materials


Physics of turbulent flow (2023-2024)


The main objectives are the mastery of basic concepts (turbulent linetic energy budget, boundary layer, role of vorticity, homogeneous and isotropic turbulence, Kolmogorov theory), the development of skills in turbulence modeling, the critical analysis of results, and a short overview of experimental approaches. Homework exercises are proposed with small classes (may involve signal processing, coding of simple models using Matlab and analytical developments), 1 practical lab session is also included. The final mark is obtained through continuous assessment.
