The wind filed in Wangyeshan, Pingtan County, Fujian Province, is simulated in this research based on fluid calculation software Fluent. The terrain information is introduced by GIS to conduct the modeling, and the wind field distribution of actual terrain under different working conditions is simulated. The velocity field of the simulated terrain under unfavorable strong wind is qualitatively analyzed, and the horizontal distribution characteristics of wind speed at different heights in the near-surface layer above the mountain are studied. The wind speeds and roughness under different wind directions and turbulence models are quantitatively analyzed by comparing the simulated results with the measured wind field to verify the accuracy of the simulation method.
