During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

Shape Optimization of a Hydraulic Turbine Using Deep Reinforcement Learning
ABSTRACT The present study explores the potential of deep reinforcement learning for the geometric optimization of a hydraulic turbine and compares its performance with that of an evolutionary algorithm. Shape optimization in fluid mechanics often leads to high‐dimensional, highly non‐linear problems, requiring efficient methods to approximate global ...

Laser surface treatment was carried out to enhance the performance of Ni‐Al2O3 coatings on HSS substrates. The results revealed improved microstructural features, corrosion resistance and significant reduction in slurry erosion wear with 18 W laser treatment. ABSTRACT The sliding wear between hydraulic vane tip and the inner surface of the cam ring can
