Making Waves: Ocean Modelling with Absorbing Wavemakers

Synopsis
Shows wavemaking facilities built at Edinburgh University Department of Engineering in connection with the Edinburgh Wave Power Project. The wide tank (30 metres wide scaled to represent 3km of ocean) with a bank of 82 computer-controlled wavemaking paddles, is shown as a versatile machine capable of modelling complex fully realistic multidirectional seas, the apparent randomness of which can be indefinitely repeated for experimental purposes. The problem of reflected waves, common to all wave tank models, is illustrated and its solution demonstrated with visual material. The force and velocity of the reflected waves themselves are used as a feedback to dampen the command signal creating new waves, thus enabling the wavemaker to absorb reflections at the same time as it generates new waves.
