The wave tank is an elongated cross-sectional model testing equipment that uses systems such as wave generators, current generators, and wind generators to manually reproduce regular waves, irregular waves, solitary waves, broken waves, and the "wave current wind" coupled dynamic environment in the laboratory. It provides an intuitive and reproducible physical testing device for marine, coastal, port, and ship engineering. Mainly used for stress and stability testing of breakwaters, docks, and revetment structures. Evaluation of energy capture efficiency and oscillating water column chamber performance of wave energy devices. Wave current sediment coupling transport and ecological embankment wave dissipation effect. Visual experiment and operation training for fluid mechanics and ocean engineering courses.
