Abstract:In order to study the flow field characteristics and dynamic fluid-structure interaction response of offshore wind turbine during operation process, the concept of integrated analysis of offshore wind power project was introduced and the simulation method for the integrated fluid-structure interaction operation process of offshore wind power was established based on the immersed boundary method. The stator-rotor interaction caused by the rotation of the fan was simulated by the immersed boundary method. With the alternating iteration method, a two-way fluid-structure interaction numerical method for the integrated research of offshore wind turbines “fan-tower-foundation” was presented. With the proposed method, the fluid-solid interaction effect of offshore wind turbine can be truly reflected and its dynamic response can be accurately solved. The immersed boundary method can effectively solve the stator-rotor interaction caused by fan rotation without updating the grid motion. Finally, the integrated fluid-structure interaction operation process of an offshore wind power project was simulated.
