Analysis of the Effect of Axial Spacing on the Performance of Counter-Rotating Axial Flow Ventilators

以FBDCZ-8-NO27型对旋轴流通风机为例,模拟分析了轴向间距对旋轴流通风机性能的影响。首先,将通风机规格尺寸、材料特性等参数录入到CFD软件内,由该软件自动构建出通风机及流体的有限元模型,并根据研究需求划分网格,然后以此为基础,分别从稳态与非稳态两个方面出发,模拟分析了三种轴向间距条件下通风机性能的变化情况,以设计出最佳的通风机轴向间距,提升通风机性能,使其在煤矿生产作业中发挥出更大的作用。

Taking FBDCZ-8-NO27 counter-rotating axial flow ventilator as an example,the influence of axial pitch on the performance of counter-rotating axial flow ventilator was simulated and analyzed.Firstly,the specification size of the ventilator,material properties and other parameters were entered into the CFD software,which automatically constructed the finite element model of the ventilator and the fluid and divided the mesh according to the research needs,and then,based on this,the changes in the performance of the ventilator under the conditions of the three kinds of axial spacing were simulated and analyzed in terms of the steady state and the unsteady state respectively to design the optimal axial spacing of the ventilator and improve the performance of the ventilator and to make it more effective in coal mining.The performance of the ventilator can be improved so that it can play a greater role in the production of coal mines.
