Large Scale Wave Flume

The wave flume is unique and world class in the range and quality of the waves it can generate. The flume is approximately 54 m long, 1.5 m wide and 1.6 m tall. Water depths of up to 1.1 m can be accommodated and two viewing windows (each 4 m long) have been installed along its length.

Wave paddles have been fitted at either end of the flume, with one set designed to produce shallow (coastal) waves using a piston mechanism and the second set designed to produce deep (offshore) waves with a rotating flap mechanism. Both paddles have state-of-the-art active wave absorption capabilities, which allows them to be absorb arbitrary reflected waves from structures being tested. The piston is a long-stroke version, with total translation of up to 2 m, enabling creation of a wide range of large and long period wave motions. The use of these two sets of paddles will make the facility unique nationally, enabling research spanning the field of coastal and offshore engineering.

This provides versatility and is vital to progress some application areas such as design of wave energy devices, which may operate in a range of wave conditions.
