Description | The hybrid model developed in this project contributes to the hybrid modelling suite, qaleFOAM, developed at the City, University of London, consisting of multiple fluid and structural mechanics solvers. In the qaleFOAM, the fluid (water and air) near the wind turbines can be modelled using the Navier-Stokes single/two- phase solvers using OpenFOAM with various options of turbulence modelling for both RANS and Large Eddy Simulation, the wave can be simulated using a full spectrum of wave models ranging from linear to fully nonlinear solvers, the blade, tower and foundation can be modelled using rigid body or linear elastic structural solver. Reduced-order models, e.g. ALM and BEM, are also available for modelling the turbine dynamics. Different coupling approaches using the time-splitting (TS), space-splitting (SS) and functional splitting (FS) strategies have been developed and incorporated in the qaleFOAM, allowing different hybrid solvers to be tailored for monolithic or partitioned fluid-structure coupling. By minimising the spatial/temporal domain for high-fidelity and time-consuming solver (the rest will be modelled by faster solvers) whilst maintaining the required degree of accuracy, the qaleFOAM has demonstrated its promising computational robustness in numerical comparative studies (e.g. Venkatachalam et al., 2021) or blind tests (Ransley et al., 2020) for highly nonlinear wave-structure interactions. The code is now released as an open source package through CCP-WSI code repository (https://www.ccp-wsi.ac.uk/code_repository/clearing_house) in github. It receives some industrial interest. Further work with industry partners in the offshore renewables is underway. |
