MTU Wave features a 10 m x 3m x 1m Edinburgh Designs wave tank with eight independently controlled paddles with position and force feedback to generate desired wave fields propagating towards an adjustable 3m long curved high-density, polyethylene, energy-adsorbing beach.
- Glass wall for observation and imaging of underwater experiments.
- Max Wave Height = 0.25 m, Wave Bandwidth = 0.3 - 1.3 Hz (0.8 - 3.3 second period).
- Time-synchronized instrumentation, including an 11 camera, Qualisys motion tracker, wave gauges, a dSPACE MicroLabBox for data acquisition and control system implementation.
- Buoy dynamometer for applying motion while measuring forces on submerged bodies.
- Overhead-mounted, 6-axis Universal Robots UR10e for force or position manipulation of objects in the wave tank.
- Overhead walkway for easy access to the wave tank and for mounting of test equipment.
- Frictionless PTO WEC control testbed.
- MTU Wave was designed with wave energy converter (WEC) technology in mind.
- Research topics include control algorithm development, fundamental hydrodynamic phenomena, validation of numerical models, and wave force machine learning strategies.
- Large motion WECs, whose models require nonlinear terms exploitable by the control system, are of particular interest.
- Validation of a CFD model of MTU Wave for fundamental hydrodynamic studies, such as the damping behavior of porous structures.
- Testing mini-thruster technologies is another area where MTU Wave is well-suited
Resistive type wave gauges to measure accurate wave elevation.
