Multiple TLDs on Motion Reduction Control of the Offshore Wind Turbines

Journal of Marine Science and Engineering, 2020
This study explores the damping effects of tuned liquid dampers (TLDs) on a monopile offshore wind turbine (OWT). The fluid–solid coupling of ANSYS was used to simulate the damping effect of a TLD on the structures.
