Wind and marine renewable energy (EMR) are key sectors to achieve the set objectives of European policy to lower carbon emissions.
INNOSEA, in collaboration with LHEEA, are working on the development of a EMR simulation software called InWave. The purpose of this software is to model the behavior of multi-body offshore systems such as wave power systems, floating wind turbines or offshore installation operations.
In order for InWave to remain competitive and be at the forefront of EMR research and new technologies, new developments must be made. Among the new features, InWave will be able to calculate complex flow forces on blades of floating wind turbines or turbines.
Scientific advances and innovation
Floating wind turbine simulators mainly use aerodynamic solvers based on stationary flow formulations. The dynamic behavior of these structures makes these approaches inappropriate for a certain number of design loading cases and in particular when the rotor is heavily loaded. The DOMTEM project aims to implement an unsteady aerodynamic solver based on a free vortex formulation being able to take into account the different non-stationary effects linked to the dynamic behavior of floating wind turbines.
Expected technical and economic impact
Develop advanced design tools to provide services through design engineering.
