Abstract

The desert areas in northwest China are rich in wind resources, and the development of wind power has been affected by sandstorms, so the relationship between the sand and dust environment and the operation of wind turbines has attracted great attention. In order to explore the influence of wind turbine wake on sand and dust transport, the large eddy simulation combined with the actuatior line method was used to study the processing of sand and dust particles by wind turbine blades and a multiphase particle grid model. Taking two horizontally axis wind turbine models as the research object, the wake states of four wind turbines with different arrangements in the wind-sand environment and the influence of the distance in the Y direction at the center of the hub of the two wind turbines on the temporal and spatial distribution characteristics of sand and dust particles were analyzed. The results show that the tandem arrangement of the two wind turbines causes a serious velocity loss to the downstream wind turbines, and the velocity loss of the downstream wind turbines with the staggered arrangement decreases with the increase of the y-axis spacing. Different arrangements of wind turbines have different effects on sand and dust transport. Under the staggerad arrangement of the two wind turbine, the sand blocking effect becomes stronger as the Y-axis spacing increases within (0-1)D. range When the Y-axis spacing is reduced, the sedimentation promotion effect is better.
