Resumen
The Ambiental impact of fishes on the presence of hydrokinetic turbines in rivers is an actual concern where there is a lack of collision risk descriptions in the literature. In this way, this works proposed a methodology to study the fish swimming on the boundaries of axial hydrokinetics turbines based on an experimental approach. An autonomous robot fish was developed to replicate the Astyanax fish, also known as Lambari, a usual species found in Brazil. The fish concept was manufactured employing 3D printing. The oscillating movement was made by one servomotor, placed inside the model, where it was controlled by a sinusoidal wave get from a mathematical model established on real swimming experiments. The main objective was to validate the hydrodynamics parameters, drag and pressure coefficient, of swimming inside the water tunnel and compare them with numerical data. We present results for the fish swimming with and without the one hydrokinetic turbine.
