摘要
为改善离心风机整体性能,文中阐述了常用的蜗壳型线设计方法,以4-72№3. 2A型离心风机蜗壳为研究对象,给出了基于基因遗传算法且考虑叶轮出口流量不均影响的蜗壳型线设计方法,绘制出了其蜗壳型线。对蜗壳改造前、后的风机进行了数值模拟和进气性能试验,并对比分析以验证移植工作的合理性。为将该设计方法工程化,利用MATLAB GUI设计并完成了该类型离心风机蜗壳型线设计软件。
In order to improve the overall performance of the centrifugal fan,this paper describes the common volute type line design method. Taking the 4-72 No3. 2 A centrifugal fan volute as the research object,the genetic genetic algorithm based on the influence of the impeller outlet flow unevenness is given. The volute type line design method has drawn its volute type line. The numerical simulation and air intake performance test were carried out on the fan before and after the volute reform,and the analysis was carried out to verify the rationality of the transplant work. In order to engineer the design method,the vortex shell design software of this type of centrifugal fan was designed and completed by MATLAB GUI.
