Recirculating water tunnel

More Information

About the Recirculating water tunnel

The recirculating water tunnel is an extensively equipped water flume used for fundamental research and industrial Research and Development (R&D). The tunnel has supported a wide range of experimental studies, including pitching aerofoils, bluff-body flows, urban aerodynamics and passive scalar mixing, with applications spanning aerospace, marine and environmental research.

The tunnel is also available for hire by commercial companies in support of their Research and Development (R&D) work. We have access to some of the world leaders in experimental fluid dynamics and can offer varying levels of support.

The tunnel is perfect for optical techniques where seeding particles can be tracked by a variety of laser and camera techniques to visualise and quantify flow structures in three dimensions.

The test section is 1.2 metres (m) wide by 0.8 m deep and can operate at up to 1 metre per second (m/s).

Technical specification

The water tunnel can be configured in various ways depending on the specific requirements of the experiment. Maximum water speed is 1 metre per second (m/s) and the tunnel incorporates a carriage system to allow for models to be moved within the tunnel.

Acquisition systems include 2D and 3D Particle Image Velocimetry (PIV) and 3D Laser Doppler Velocimetry (LDV).
