摘　　要：阐述了垂直吸风道风选器工作原理、结构及Fluent软件数学模型理论。运用商用有限元软件Ansys workbench中的Fluent模块对垂直吸风道风选通道内的气流速度、气流分布形式进行了仿真分析。并针对问题对初始边界条件的设定、收敛性与稳定性、模型后处理等问题作出阐述。根据仿真分析以及物料在气流场中的运动规律和存在的问题,对通道形状及进气口尺寸进行了改进,进一步提高了粮食除杂效率,减小了设备体积并降低了能耗,为垂直吸风道风选器的优化设计提供了理论依据。We expounded the working principle and structure of air-float separator of vertical suction duct and mathematical model of Fluent software, used the Fluent module of the commercial finite element software （Ansys workbench） for simulation analysis of the air speed and air flow distribution in vertical suction duct, described the initial settings of boundary conditions, the convergence and stability, the model after processing problems and so on. According to the simulation analysis and the movement rule of solid particles in the gas flow field, we improved the channel shape and inlet size, further improved the cleaning efficiency, reduced the volume of equipment and energy consumption, which provided a good basis for the optimization design of air-float separator of vertical suction duct.
