Modellgestützte Entwicklung und Untersuchung des Wendelfischpasses
摘要
The spiral fish pass enables fish migration both upstream and downstream in confined spaces. The multi-phase commissioning of a corresponding model in the hydraulic engineering research laboratory and the evaluation based on measured data facilitated the adaptation of a numerical flow model as a digital twin. The laboratory studies demonstrated how water depths and flow velocities can be adjusted through flow-modulating installations for various locations and fish species. Aperiodic flow pulsations and their effects were examined to further enhance functionality in the future.
