Laurent Jacquin passed away on September 21, 2024. An aerodynamicist specializing in turbulence and vortex flows, Laurent was department director and then scientific director at ONERA and professor of fluid mechanics at École Polytechnique. To pay tribute to him and celebrate his legacy, we are organizing a scientific conference on September 10, 11, and 12 at École Polytechnique in Palaiseau.

The conference will take place on the Ecole Polytechnique campus at Palaiseau, in the amphitheater of the "pôle de mécanique" (bâtiment 104).

Registrations are free but mandatory and need to be done through this website: if you do not have already a sciencesconf account, you will have to create one to register. Short oral presentation are welcome and should be submitted through this web site (My Submissions).
