Numerical simulation of wind field over complex terrain and its application in Jiuzhaihuanglong Airport
A numerical simulation method for the wind field over complex terrain was developed.The complex terrain was represented by a surface,which was established by the surface spline method based on the contour line of the map.Then it was divided into panels containing vortex ring singularities.The singularity distribution was solved by combining with the potential flow theory and the boundary condition of terrain surface.Finally,the wind filed was simulated by linear superposition of uniform stream and induced velocity of vortex rings.An example was studied,and the result was also compared with Weather Research and Forecasting(WRF)method.It indicates that the method proposed could describe the terrain much more accurately and provide a reasonable result of wind field distribution.
