The hydrodynamic water tunnel of Boulogne/Mer
The water circulation basin of Boulogne/Mer
has a very rapid water circulation (2 m/s). Its hydrodynamic
characteristics are excellent and allow, with the specific instrumentation such as a laser velocimeter, to carry out
various activities such as sub-marine vehicle drag measurements and fishing gear behaviour tests.
The water tunnel has the following characteristics:
- Length: 18 m
- Width: 4 m
- Height: 2m
- Length of observation window: 8 m
- Length of mobile bottom: 9 m
- Speed of water: from 0,15 m/s up to 2 m/s
- Mobile carriage for placing equipment in water and for
observation
- Associated measurement devices: laser
velocimeter 2 directions.
The Main activities which are carried out:
Hydrodynamic tests and studies on scale model (or full-scale if they are of small size) on vehicles towed
along the bottom (fishing-gear), propelled or anchored, in either fully
submerged or
at the surface (seismic instrumentation).
