Instrumentation

The Boulogne-sur-Mer flume tank is equipped with whole and performance measurement facilities specific to hydrodynamics.

In particular it provides measurements of main mechanical stresses on testing devices and allows to study and visualise the water flow and the dynamical behaviour of the models :

• Laser Dopler Velocimeter (LDV)
• Particle Image Velocimeter system (PIV)
• Components load-cells (3 or 6)
• A 3D air and submarine motion tracking system
