LHEEA - News & events

The Centrale Nantes campus will play host to the 19th edition of the Hydrodynamics Days (Journées de l'Hydrodynamique), organised by the Research Laboratory in Hydrodynamics, Energetics & Atmospheric Environment (LHEEA) from Tuesday 26 to Thursday 28 November 2024.

This symposium is the worldwide meeting of specialists in research and development in fluid mechanics as they relate to naval hydrodynamics.

As part of the ExplOr project funded by the Institut CARNOT MERS, an intensive measurement campaign combining wind, wave and aerosol measurements by LiDAR scanning was carried out at Belle-île-en-Mer over the period March-July 2023. The aim of the combined measurements is to document wind-wave interactions over the sea.

10 years after the installation of the export cable, the SEM-REV marine renewable energy test site has enjoyed further investment. The aim was to upgrade the site and pave the way for hosting future prototypes. Thanks to funding from the French State, the Pays de la Loire Region and Europe, which Centrale Nantes applied for as part of the "France 2030" programme, the site has been able to connect new prototypes since April.

Philippe Spalart studied Mathematics and Engineering in Paris, and obtained an Aerospace PhD at Stanford/NASA-Ames in 1982. Still at Ames, he conducted Direct Numerical Simulations of transitional and turbulent boundary layers. Moving to Boeing in 1990, he created the Spalart-Allmaras one-equation Reynolds-Averaged Navier-Stokes turbulence model. He wrote a review and co-holds a patent on airplane trailing vortices. In 1997 he proposed the Detached-Eddy Simulation approach, blending RANS and Large-Eddy Simulation to address separated flows at high Reynolds numbers with a manageable cost. He became a Boeing Senior Technical Fellow in 2007, was elected to the National Academy of Engineering in 2017, and received the AIAA Reed Award for 2019. His papers have been cited 45,000 times. Recent work includes refinements to the SA model and DES, computational aeroacoustics, theories for aerodynamics and turbulence, and the design of research experiments. Philippe retired from Boeing in 2020.

Velella aims to develop several technological components and methods needed to prepare the deployment of commercial floating wind projects under the best economic, social and environmental conditions.

The FOWT 2023 conference (Floating Offshore Wind Turbines) will be held in Nantes on 10 and 11 May. These two days will be followed by technical visits, one of which will take participants offshore to visit the SEM-REV site.

Investment on the SEM-REV site continues! After receiving the site's new cables and connectors, the teams, led by INYANGA, have completed the installation of the connectors on the cables and prepared them for the installation offshore.

The Master in Renewable Energy in the Marine Environment (REM+) was awarded a World Maritime Week 2023 prize in the category of marine energy in Bilbao, Spain on 23 March 2023.

Centrale Nantes is proud to be one of the founding members of the OPEN-C Foundation and of our role in creating the largest European offshore testing facility, as pioneered by our SEM-REV test site.

The European research project FLOATECH is back at the LHEEA's wave and ocean engineering tank for a second test campaign. The teams involved continue to study the hydrodynamic forces that impact a floating wind turbine in order to improve its performance.

The Mervent 2025 project led by Zéphyr & Borée and its partners CWS, GTT and Centrale Nantes was selected as part of the CORIMER Call for Expression of Interest 2022. Mervent aims to build the first container ship powered by hybrid sail/synthetic fuel.

In 2022, the offshore test site SEM-REV began a phase of investment and works to enhance its capacity to host new demonstration and research projects. Following the award of the underwater equipment supply contract launched in 2022, a consortium, led by INYANGA, recently delivered the new submarine cables and connectors.

Building on their long-standing collaboration with Nextflow Software, Centrale Nantes and Siemens Digital Industries Software are stepping up their cooperation in the field of numerical simulation applied to fluid mechanics by launching a new joint research chair. The agreement provides for multi-year funding to the tune of several million euros, with the aim of keeping both organisations at the forefront of digital simulation technology using SPH methods.

Centrale Nantes was present at the 6th edition of the 'Nuit Blanche des chercheurs' organised by Nantes University on 2 February 2023.

Behavior and aging modeling of a battery used for automotive propulsion

Join us on Thursday 2 February 2023 at Stereolux, Hall 6 West. For this new edition of the "Nuit Blanche des Chercheurs" in Nantes on the theme "Vibrations". Come along and discover the buzzing world of research in Nantes! Centrale Nantes' research teams will give presentations on themes ranging from Marine Renewable Energies to earthquakes and the properties of explosions!

Compact High-Order Accurate Scheme for Laminar Incompressible Two-Phase Flows

Hubert Chanson, professor at the University of Queensland (Australia), is at Centrale Nantes on the invitation of the LHEEA - Research Laboratory in Hydrodynamics, Energetics and Atmospheric Environment (Centrale Nantes/CNRS). His lecture "Fluid Mechanics applied to Natural Disasters" will take place in lecture theatre E from 4:00 pm to 5:30 pm. It will be held in English.
