The water towing channel has a length of ca. 8 m and a cross-section of ca. 0.9 x 0.9 m². In contrast to conventional wind and water tunnels, with the water towing channel the fluid is at rest. The model is towed by means of a traverse. This has the great advantage that the achieved turbulence level is extremely low, which is important for experiments in the field of transition research. In addition, wake effects can be observed over a long period of time, which is not possible in conventional tunnels.

The maximum towing velocity is 1 m/s, whereby the acceleration can be defined in the starting process. This allows the targeted investigation of e.g. the development of starting vortices.
