The tank, approximately 120' long, 12' wide and 8' deep, offers a 90' test length in which test bodies can be towed, subjected to wave action, or both. The Tow Tank is used for a variety of ocean engineering research projects as well as commercial science. Click here to learn more.
The tank includes an on-board electronics cabinet which provides enough continuous on-board power to run state-of-the-art measurement tools, e.g. particle image velocimetry (PIV). It also contains auxiliary servo drives for automated instrument positioning and/or turbine speed control. The data acquisition system allows streaming of measurement data over Ethernet to the main host PC, providing improved integration and synchronization.
Wave creation is possible using a hydraulic flapper style wavemaker which can produce 2 to 5 second waves of maximum amplitude 0.5m. The wave destruction or ‘beach’ is a saw tooth style geo-textile construction which has an average 92% efficiency in the frequency range specified.
The tank's motion and control system is a belt-driven AC servo system, providing precise positioning capabilities with maximum acceleration and tow power.
The wave maker software allows tank users to develop regular or random seas using a variety of spectra such as Bretsneider, JONSWAP, and Berskon-Moskowitz. The 32-bit user interface is written in LabView and resides on the main control station PC.
