Hydraulic performance of fish guidance structures with curved bars – Part 2: flow fields
(2020)Journal of Hydraulic ResearchThe current geometric designs of fish guidance structures with vertical bars for run-of-river hydropower plants result in high head losses and asymmetric turbine admission flow. To address these issues, we develop innovative curved bar designs and experimentally investigate different rack configurations with curved bars in a laboratory flume. The present paper (Part II) focuses on the hydraulic performance of the novel curved bar designs ...Journal Article -
Hydraulic performance of fish guidance structures with curved bars – Part 1: head loss assessment
(2020)Journal of Hydraulic ResearchThe hydraulic performance of fish guidance structures such as louvres and angled bar racks is an important design criterion to achieve high fish guidance efficiencies with a minimum impact on hydropower production. The current geometrical designs of such structures result in high head losses and asymmetric turbine admission flow and hence need to be optimized. We therefore developed an innovative curved bar design for fish guidance ...Journal Article
