Wind Field Simulation of Capital Airport Based on Lidar Data
The low-level wind effect refers to the phenomenon that the airport structure or other artificial structures located near the runway cause significant disturbance to the airflow under certain wind conditions. This effect is likely to cause turbulence or even wind shear, and bring difficulties to the aircrafts’ takeoff and landing. The computational fluid dynamics(CFD) method was adopted to simulate the wind field at Capital Airport, Beijing, China. To overcome the limitation of CFD in the setting of input wind speed, high-precision and high-resolution data measured by lidar were introduced into CFD as input condition to investigate the influence of buildings and artificial structures on wind speed at Capital Airport. The simulation results show that when the wind speed of 11~15 m/s under northwest wind condition was applied, the air flow near east runway was influenced significantly. The same situation happened in the west runway and the middle runway under the south wind condition with the same wind speed.
