CORIOLIS PLATFORM

Since 2018 I am in charge of the scientific direction of the Coriolis Platform.

​

The Coriolis platform, measuring 13 m in diameter, is the largest rotating platform in the world dedicated to fluid mechanics. Its main activity is the experimental modelling of geophysical flows, taking into account the Earth's rotation, with or without density stratification or topography. The large dimensions allow the inertial regimes that characterise ocean dynamics to be approached, with little influence from viscosity and centrifugal force. The laboratory experiments thus make it possible to test the ocean dynamics models and develop their physical parameterisations.

The Coriolis platform was rebuilt in the LEGI premises in St Martin d'Hères in 2014 on the model of the old Coriolis I platform, built in 1960, with improved performance.

​

The scientific support of the Coriolis Rotating Platform consists in adapting the scientific project and in the conception, design and coordination of the experiments in close discussion with the users, in assisting and supervising the experiments and in the primary data management and post-processing to produce data files that can be further exploited by the external users. This latter task also includes ad-hoc calibrations and new developments of the existent softwares (e.g. UVMAT) for PIV/LIF and also the data processing from other instrumentation such as probes and acoustic doppler devices. I further participate in the discussion and physical interpretation of the results as well as in writing articles.
