Cavitation Tunnel.

Túnel de Cavitación en la vista en planta

The Cavitation Tunnel of CEHIPAR, is used to check and optimize propeller design by observing the cavitation inception and development, erosion risk, pressure fluctuations and noise generation. The tests can be performed with the propeller in free-stream, behind a screen simulating the ship wake, or introducing a dummy body (partial model of the ship hull). Non-conventional propulsors are also tested.

The measurement system includes a Laser-Doppler anemometer for non-intrusive measurement of the velocity of the water.
