Determination whether a large scale Tesla valve could be applicable as a fish passage

Additional Thesis - All around the world many species are dying out locally or entirely due to interferences in their habitats. One of the big problems for marine life is the creation of migration barriers which preclude migrating species to complete their life cycle.Fish passages are a way for migrating species to get around obstructions in a water way. The goal of this research is to determine whether a large scale Tesla valve could be applicable as a fish passage. In a series of three experiments is investigated whether a large scale Tesla valve can meet the requirements as a fish passage. The three experiments have different scales and in each experiment focuses on another part of the requirements. Taking into account all the points from both the ecological and technical perspective it is determined that a large scale Tesla valve could indeed be applicable as a fish passage. However in its original design the valve will only be applicable as fish passage in cases of (very) small gradients and in cases of high gradients only in combination with large discharges. Further research has to be done on shape optimisation, the critical flow velocity and constructional & economic feasibility before the general feasibility of a large scale Tesla valve as fish passage can be determined.
