For the first time, researchers at D-BAUG have measured air-water flows with velocities exceeding 40 m/s. To this end, two challenging measurement campaigns were carried out in the tunnel spillway of a 225 m high dam, for which special probes first had to be developed. With the new data, existing design guidelines can be validated, and so-called scale effects can be assessed more accurately. This is relevant for the safe operation of hydraulic structures.
