Overview

Module Turbine is in charge of calculating the force exerted by turbines in the water flow as well as the power and energy extraction. This implementation is available for 2D and 3D simulations being, in the 3D model, only discretised in the vertical domain. There is no discretisation of the turbine geometry (and force) in the horizontal domain, the model computes the force as a punctual force in the cell where the turbine is placed.

For the moment, the model is thought for horizontal bidirectional turbines, with pitch control and free rotation in the vertical axis (the perpendicularity between flow and turbine is implicit in the model as the force is introduced into the hydrodynamic model as a punctual force).
