Abstract:
The turbulent flow study in vertical slot fishway is necessary to improve this crossing device containing physical barriers to fish migration. Effectively, studies of existing fishways have shown their limits to ensure the crossing of small fish species with weak swimming abilities. The objective of our study is to adapt the turbulent flow to the fish species swimming abilities. The two-dimensional velocity measurements by Particle Image Velocimetry (PIV) and three-dimensional velocity measurements by Doppler Velocimetry Acoustics (ADV) have shown that the flow kinematic quantities within the existing fishways are very important next to the small fish species capacities. One of strategies to answer at this problem is to introduce obstacles with cylindrical shape in the fishways pools. The adjunction of cylinders is intended to reduce the kinematics quantities of the turbulent flow within the fishways in order to adapt this hydraulic structure to the passage of small fish species. This strategy requires an optimization method to find the ideal location of the cylinders from numerical simulations of the flow (Star-CD code).
