Characterization of the Wave Profile in the Edinburgh Curved Tank

A novel wave tank has been in use at the University of Edinburgh since 2003. Its main innovation is in the layout of the absorbing/wave-maker paddles, which are arranged in a 90-degree arc in an attempt to improve the angular spread of the generated three-dimensional sea states, and to minimise cross-tank seiches. This paper reports on current studies that aim to assess the quality of the waves in the tank. Directional regular and irregular wave analysis is conducted using data from two arrays of wave elevation probes. Comparisons with the expected wave patterns are made. Emphasis is given to the description of the experimental methodology. The study should prove particularly relevant in the design of a future circular combined wave and current tank.
