To study the distribution characteristics of wind parameters near the shore, a two-dimensional geometric model is established based on CFD (computational fluid dynamics) technology. Because of the two-dimensional wind action on a calm water surface, the SST k-ω turbulence model and multiphase flow model are adopted to numerically simulate the distribution characteristics of wind parameters. The changes in development distance, water depth, incoming wind speed, and slope of underwater terrain on the distribution characteristics of wind parameters are analyzed. The results show that when the development distance is less than 60m, the wind speed near the water surface is larger than the inlet wind speed, showing an accelerating phenomenon. When the wind speed exceeds 60m, the wind speed increases with the increase of the position height, and the speed remains unchanged after reaching a certain height. The variation of slope does not affect the distribution characteristics of wind parameters. Water depth has a strong correlation with wind parameter characteristics. The increase in water depth will lead to a nonlinear increase in gradient wind height and has a great influence on wind speed. The inlet wind speed does not affect the gradient wind height and wind structure but will affect the acceleration effect near the inlet. The change of wind attack Angle has a strong correlation with inlet wind speed and water depth. With the increase of wind speed, the change of wind attack Angle is more obvious. Generally, when the wind speed increases, the wind attack Angle will change greatly.
