LadhyX - Laboratoire d'hydrodynamique de l'Ecole Polytechnique

LadhyX has been involved in numerical, theoretical and experimental studies on stratified flows with a focus on the layering phenomenon for the past 10 years. It has performed numerous instability studies in the context of stratified fluid, and contributed to the recent advances in the understanding of stratified turbulence. He has also a strong experience in vortex generation as an experimental approach to stratified turbulence.

In this project, LadhyX will apply this expertise to rotating flows, in link with the other partners.

The Hydrodynamics Laboratory (LadHyX) was established in 1990 in order to foster the growth of fundamental studies in fluid mechanics. LadHyX is jointly supported by Ecole Polytechnique and the National Center for Scientific Research (CNRS) (UMR n°7646). It is part of the Department of Mechanics at Ecole Polytechnique. LadHyX researchers actively participate in all the academic programs within the department of Mechanics, particularly in the Master of Mechanics.

As much as possible, we try to include on any given topic, theoretical, numerical and experimental components, the experiment serving as a focus for the investigations. Most of the research projects in LadHyX are of a fundamental nature. However the flows of interest are frequently encountered in natural phenomena and in industrial applications. The LadHyX group's approach to research is based on cultivating and maintaining close links between experimental observations and theoretical developments, between classical hydrodynamics and nonlinear physics and between fundamental and more applied investigations.

The laboratory is fully involved in the activities of the French Mechanics community (memberships in several coordinating research groups sponsored by CNRS, participation in national and international review panels, editorship of journals, organisation of international conferences, collaborations with industrial partners in the public and private sectors). It also maintains close relations with research teams working on similar topics in Europe and North America. Visitors from abroad regularly spend extended or short-term periods in the laboratory. A semi-weekly series of LadHyX seminars is held every other Thursday.
