The project aims to investigate the importance of fully nonlinear simulations of marine renewable energy with special focus on floating wave energy converters (fWECs). The power production from fWECs is today computed with linear models. Although fast, the accuracy of these methods close to resonance and in large waves is uncertain. Access to advanced models that includes non-linear effects of e.g. viscosity, over-topping and breaking waves is therefore vital for improving device performance without costly field trials.
To simulate real sea states in CFD is a computationally very demanding task due to long-time (1000 wave periods) unsteady simulations and access to HPC resources is vital for the success of the project. The allocation will be used mainly for two ongoing projects: “IAE-OES Task 10 - Code to Code Comparison of wave energy modeling” supported by the Swedish Energy Agency and “Multifidelity Decision Making Tools for Wave Energy Systems” supported by OceanEra-Net.
