摘　　要：利用计算流体动力学(CFD)软件Fluent对OFDY-1.2型可移动式风蚀风洞中模拟典型农田风蚀地表风速廓线进行数值模拟,通过改变棒栅、尖塔和粗糙元的尺寸、形状和位置,分别用软件和室内风洞实验模拟出了与野外实地测试廓线相吻合的风速廓线。同时,对野外实测、室内风洞模拟和软件数值模拟的风速廓线进行了离散程度分析。The paper used Fluent, a software of computational fluid dynamics, to simulate the OFDY - 1.2 transportable wind - tunnel indoor test in numerical. The test simulated wind speed contour line of typical wind erosion surface used the stick grid, steeple and rough unit. The research simulated the speed contour line by changing the size, shape and position of simulative equipments. The end of the article analyzed discrete degree of the wind speed contour line which made by the software, the wind -tunnel indoor test and the field measurement.
