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 ...).

Experimental platform of the IIHNE team: Ocean Tanks

Towing tank

The towing tank at Centrale Nantes is 140 m-long, 5 m-wide, with a constant depth of 3 m. It is equipped with a towing carriage able to move in both directions, at speeds up to 8 m/s.

Hydrodynamic and ocean engineering tank

50 m long by 30 m wide and 5 m deep, the tank is equipped with a segmented wave beater composed of 48 independent flaps to generate directional waves. A wind generating system producing an air flow of 3m by 3m section with speeds up to 15m/s can be placed above the tank.

Shallow water tank
This tank measuring 20m x 9.5m x 1m is equipped with two mobile and motorized footbridges that overhang it. They allow the installation of equipment or instruments. It is also equipped with a unidirectional wave-type beater.

Recirculating canal

This canal has a test vein of 2 m wide and about 10 m long. The maximum use depth of the basin is about 1.10 m. A part of the test vein is equipped with glass side walls (1.6 m wide), allowing visual observation of the flow, as well as measurement, for example by laser velocimetry, of fluid velocities. It is used for studies of marine propulsion systems, turbine performance, stationary flows and stabilization (appendages, foils, fins, etc.)
