127492 - Numerical Research on the Aero-Hydrodynamic Coupling Performance of Floating Vertical-Axis Wind Turbine 

With the continuous evolution of the global zero-carbon emission process, offshore floating wind power has gradually entered people's vision. Meanwhile, compared to large horizontal axis wind turbines, vertical axis wind turbines have the advantages of low center of gravity, easier installation and maintenance, and are considered by researchers as one of the solutions for future floating wind power. Due to the particularity of the motion of the vertical axis fan, it is difficult to completely use the research method of the horizontal axis wind turbines for the existing hydrodynamic and aerodynamic coupling solution of the floating VAWT. In this paper, the CFD numerical method based on finite volume method is used to solve the coupling solution of the two-phase flow motion of H-type floating VAWT. The three-dimensional incompressible N-S equation is selected as the fluid control equation in the simulation. The VOF method is used to accurately solve the free liquid surface shape. The six-degree-of-freedom (6 DOF) equation is used to solve the motion attitude of the VAWT. The velocity entry wave making method is used to create numerical waves. In the simulation, different wind speeds and wave parameters were considered as the boundary conditions and initial conditions. Under different cases, by changing the rotation speed and shape of the floating VAWT and summarizing the calculation results, the motion law and aero-hydrodynamic coupling performance of the floating VAWT under wind and wave conditions can be obtained.
