By taking the NREL-5MW stationary wind turbine as the research object, the CFD method combined with the slip grid technique is used to simulate the hydrostatic environment and a variety of wave steepness environments, and the effects of these marine environments on the aerodynamic performance of the wind turbine as well as the corresponding wake field are analyzed. The results show that: the introduction of two-phase flow environment will have a significant coupling effect with the wake field, and at the same time, it affects the pressure distribution of the turbine blades, which increases the pressure coefficient of the blades; the increase of wave steepness affects the pressure distribution of the blades during the wave week, and it also makes the wave period and the tower shadow effect control the oscillating frequency of the turbine power, the thrust time calendar curve, and at the same time, it significantly affects the attenuation dissipation in the wake field of the turbine.
