Circulating Water Tunnel

Circulating Water Tunnel

The circulating water channel is designed for lower and medium speeds. The design permits the manufacture and operation of a channel with a relatively large measuring section at still moderate cost. The pressure above the water surface can be reduced to slightly above vapour pressure. So the Cavitation numbers below Æ = 0.1 can be reached at the water surface in the measuring section. Due to the moderate water speed, the cavitation number is quickly increased with water depth.
