Wind-Wave-Current Multifunctional Laboratory

Wind-Wave-Current Multifunctional Laboratory is the first large-scale boundary layer wind tunnel facility in China capable of simultaneously simulating the coupling effects of multiple natural hazards, including strong winds, waves, ocean currents, tornadoes, and downbursts. This advanced laboratory enables experimental research on long-span bridges, buildings, offshore wind turbines, wind environments, and wind-wave-current coupling effects.

• Vertical Closed-circuit Wind Tunnel

Low-Speed section dimensions: 8 m (width) × 4 m (height), maximum wind speed 18 m/s

High-speed section dimensions: 4 m (width) × 3 m (height), maximum wind speed 48 m/s.

• Wave-Current Flume

Wave-current flume dimensions: 31 m (length) × 4 m (width) × 3 m (depth), maximum water depth 2.2 m. Maximum wave height 0.6 m. Maximum flow velocity 0.7 m/s. It is capable of simulating regular and irregular waves, and is equipped with a movable floor and scour sediment tank.

• Localized Strong Wind Simulator

The tornado and downburst simulators can operate independently outside the wind tunnel. The distance from the outlet to the test platform is adjustable from 0.1 m to 0.6 m. They can be moved into the low-speed test section via a rail system to simulate localized strong winds considering boundary layer turbulence.
