摘要
利用成熟的计算流体软件,对布置多个支撑观测仪器的支架所导致的大气边界层风场失真进行定量仿真,在此基础上给出了降低对真实风场干扰的涉及支架间距、支架连线与风向夹角、以及支架与测量仪器的间距等的一种优化布置方案,该方案能使风场失真率小于3%.
A widely applicable CFD software was used to simulated the flow around multiple meteorological observation masts and the distorting influence of the masts on the flow field around them was analyzed. Ba^ed on a quantitative calculation, an optimized observation scheme was suggested, which considered the distance between two contiguous masts, the angle between the incoming wind direction and the line along which masts were located at, and the distance between mast and observation instrument mounted on it. The result indicated that this optimized scheme could effectively reduce the influence of the masts on a wind field and the distortion of wind field was less than 3%.
