本文应用有限元方法,建立了横流式农用清选风机内部的气体流动数值模拟模型。该方法避免了以往的计算方法在复杂边界上的繁琐处理,使分析过程大大简化。经过计算分析与实验比较,其结果是令人满意的。这种分析方法对横流风机的理论分析及结构优化设计具有一定的实际意义。
In this paper, the finite element method is used to establish a numerical simulation model of gas flow inside a crossflow agricultural purifying blower. This method avoids the cumbersome processing of the complicated calculation methods in the past and greatly simplifies the analysis process. After calculation and analysis and experimental comparison, the result is satisfactory. This kind of analysis method has some practical significance to the theoretical analysis and structural optimization design of cross flow fan.
