Mixed research unit Centrale Nantes/CNRS(UMR 6598)

The LHEEA is tasked with both advancing theoretical knowledge and resolving concrete problems around four scientific themes:
  • free-surface hydrodynamics,
  • fluid-structure interactions,
  • dynamics of the atmosphere,
  • systems approach for ground and marine propulsion systems.

Respond to strong societal and technological issues

  • Performance of Marine Renewable Energies (MRE) systems (offshore wind, floating offshore wind turbines, tidal, wave energy...)
  • Safety of both people and equipment involved in marine activities
  • Reduction of polluting emissions associated with ground and maritime transport
  • Quality of the urban atmosphere

The LHEEA tackles its research problems by implementing a combination of approaches: numerical simulation (development and use of modeling software, especially in Computational Fluid Dynamics-CFD), experiments at model scale (engine test benches, ocean and wave tanks, atmospheric wind tunnels) and in-situ experiments (SEM-REV, offshore sea test site).

5 RESEARCH TEAMS

DAUC | Dynamics of Urban and Costal Atmosphere

Investigating the dynamic and thermodynamic processes that take place in the lower atmosphere in urban and coastal environment, and their interaction with surfaces is the main research interest of the group Dynamics for urban and coastal Atmosphere (DAUC).

SEMREV+ | Development, modelling, optimisation & testing of renewable energy systems in the marine environment

SEMREV+ research activities focus on the development, modelling, optimisation and testing of renewable energy systems in the marine environment (marine renewables energies including offshore wind).
The SEMREV+ team deploys a combination of experimental and numerical approaches, depending on the physical problems to tackle. In this respect its research activities are strongly linked to the SEM-REV offshore test site.

IIHNE | Interfaces & Interactions in Numerical & Experimental Hydrodynamics

The IIHNE research group is studying complex hydrodynamic flows in interaction with marine structures.  The group's research can be applied to problems in marine engineering (naval, offshore, EMR) and performance or safety of marine structures. The research group also works on experimental and numerical modeling of the dynamic behavior of marine structures and systems (ships, wind and hydroelectric platforms, submarines, sailboats, etc.) under the effect of external forces (waves, winds, currents ...) or internal (Safran, mobile appendices ...).

METHRIC | Modelling of Incompressible Turbulent Flows at High Reynolds numbers and Couplings

The objective of the METHRIC group is the numerical modeling of turbulent flows of incompressible viscous fluids around complex geometries under real conditions. This concerns both hydrodynamics and low-speed unsteady aerodynamics within the limit of incompressible fluid assumptions. The group's research provides an understanding of vessel-propulsion interactions under real conditions in order to optimize the energy performance of ships.

D2SE | Decarbonization & depollution of energy systems

The research focus of the D2SE research group is the modeling and experimental characterization of complex energy systems with the aim of reducing fossil fuel consumption and polluting emissions. The group has established strong links with the industrial environment, since its field of research has strong societal and environmental impacts.
