Title: Numerical Simulations of Complex Wake Flows of Floating Offshore Wind Turbine
Abstract:
In this presentation, an in-house FOWT-UALM-SJTU solver is introduced to achieve
fully coupled aero-hydrodynamic simulations of floating offshore wind turbines
(FOWTs) based on the unsteady actuator line model (UALM). The performance of wind
turbine-floating platform-mooring system can be also predicted. The FOWT-UALM-
SJTU solver can also simulate two wind turbines with in-line and offset layouts, and
predict the aerodynamic loads, wake characteristics, vortex structure and the complex
wake interaction phenomenon, and analyze the wake development and wake interaction
among wind turbines in yaw condition. With the FOWT-UALM-SJTU solver, a
numerical investigation has been executed based on the Lillgrund wind farm layout to
discuss the aerodynamic loads, complex wake effects and significant wake interactions.
By combining overset grid technique and in-house CFD hydrodynamic solver, naoe-
FOAM-SJTU, the fully coupled aero-hydrodynamic simulations of floating offshore
wind turbines are also presented.
