Circulating Water Channel

Circulation Water Channel<

The circulating water channel is a newly reconstructed facility that is a 1:14 scale model of the US Navy's Large Cavitation Channel located in Memphis, Tennessee. The channel test section measures 93cm long by 22cm wide by 22cm high. It is equipped with a 6:1 contraction and a diffuser section, and powered by a 200 horsepower open loop AC drive motor capable of producing maximum flow speeds of 25ms-1/50 knots.

This facility was designed to conduct research on cavitation, loads on components of marine vehicles, and friction drag reduction by various techniques including air layers. The purpose of these latter experiments is to understand the underlying physics of air layers and how this technology can be used to reduce drag on high speed marine vehicles.
