{pt_PT=Implementation of the effect of turbines on water currents in MOHID Modelling System} {} EVALUATED

{pt=The present document describes the project of including into the hydrodynamic model of MOHID Studio application the effect of turbines on water currents. This implementation intends to be a reliable tool for promoting renewable energies that make use of hydrokinetic energy, as tidal stream energy. This model allows users to study flow modification and energy extraction as well as other sub-consequent effects as sediment transportation and water level. The implementation is designed for axial turbines that can work on both directions, with free rotation on the vertical axis and pitch control for the power harvested. It can work in 2D and 3D simulations, even though the turbine is only discretized in the vertical direction (for 3D simulations only), not in the horizontal plane. The horizontal resolution, in order to obtain useful results, must be as little as the dimension of the turbines blades. In low resolution of the grid the application works well but the results are graphically inaccurate. The programming is made in Fortran90, the same language as the MOHID Studio application. The code, which is not included in this memory, can be found in MOHID github repository, en=The present document describes the project of including into the hydrodynamic model of MOHID Studio application the effect of turbines on water currents.
