Abstract

Turbulence features in a operating vertical slot fish pass were explored first by means of analyzing in situ ADV data. The mean velocity field its vorticity and important turbulence parameters were quantified. The swirling character of the flow was made visible, and the vertical velocity component proved to play an important role at places. As to turbulence features, the Eulerian space-scale provided valuable information on the dominant eddy size in the flow, expected to contribute to the detailed flow structure dependent analysis of the swimming performance of fish in various fish pass facilities. The order of magnitude of this eddy size was found quite close to the one of the fish migrating there. As a future design tool, a first implementation of the 3D k-ε SSIIM model was carried out and provided promising primary results. The CFD model could reasonably reproduce the important elements and overall complexity of the mean flow field typical to vertical slot fish pass arrangements.
