Functions

The StreamliNZ flume uses the latest technology to create a unique aquatic environment. It resembles a treadmill, but with a channel of precisely-controlled flowing water instead of a walkway. It is designed specifically to enable a wide range of functions including highly-accurate scientific research and testing in a controlled aquatic environment.

Potential usage includes:

• Sports performance
• Safety
• Rehabilitation
• Teaching
• Research
• Commercial Development

Water speed is controllable from 0 to 2.5 m/s or 3.2 m/s depending on flume choice/design. The flume has an optimal water flow quality operating speed of 1.8 m/s. Water flows in a channel 2.5m wide, 1.5m deep and a channel length depending on customer requirements from 6m to 10m. Effective channel width not influenced by the edge effects is 2.3m at 2 m/s.

There are above-water viewing areas to the side and rear of the flume, a movable gantry/platform above and underwater viewing from the side.

Video cameras provide multiple views of swimmers and can be used for biomedical analysis and technique development.

Load cells can also be used to evaluate lift and drag on objects in the flume.
