Context
Wind energy and marine renewable energy (MRE) are key sectors for achieving the European policy objectives of reducing carbon emissions.
INNOSEA, in collaboration with LHEEA, is working on the development of MRE simulation software: InWave. The aim of this software is to model the behavior of multi-body offshore systems such as wave energy converters, floating wind turbines, and offshore installation operations.
In order for InWave to remain competitive and at the forefront of EMF research and new technologies, new developments must be made. Among the new features, InWave will be able to calculate complex flow stresses on floating wind turbine blades or tidal turbines.
Scientific breakthroughs and innovation
Floating wind turbine simulators mainly use aerodynamic solvers based on steady-state flow formulations. The dynamic behavior of these structures makes these approaches unsuitable for a number of loading cases, particularly when the rotor is heavily loaded. The DOMTEM project aims to implement a non-steady aerodynamic solver based on a free vortex formulation that takes into account the various instabilities associated with the dynamic behavior of floating wind turbines.
Expected technical and economic impact
Develop advanced design tools to provide services through design engineering.
Results
- Complete encapsulation of the OpenFAST Aerodyn module and software interface for coupling with seakeeping software
- Development of a free vortex wake solver
- Evaluation of the performance of the free vortex wake solver for application to the calculation of interactions between multiple Flettner rotors
Industrial benefits
Have a more accurate sizing tool that enables more refined design with the aim of reducing LCOE.
