The paper used Fluent,a software of computational fluid dynamics,to simulate the 0FDY-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 ...
