摘要
针对最新研制的4MZ-4自走箱式采棉机,为分析其风送系统流动特性,并使风量在四个输送管路中分配均匀,利用Hypermesh、Fluent软件对四行机离心风机及一分四歧管进行了流体域建模及数值分析,分析得到离心风机出口流量数据,以风机出口流量作为歧管入口边界条件计算歧管各出口流量及流量配比,并根据歧管内空气流动状态对歧管结构进行优化,优化后歧管的风量配比均匀性得到显著改善.
Abstract
For the newly developed 4MZ-4 self-propelled box type cotton picker,in order to analyze the flow characteristics of its air supply system and ensure uniform distribution of air volume in the four conveying pipelines,CFD modeling and analysis were conducted on the four lines centrifugal fan and one quarter manifold using Hypermesh and Fluent software.The outlet flow data of the centrifugal fan was analyzed,and the outlet flow rate of the fan was used as the boundary condition of the manifold inlet to calculate the flow rate and flow ratio of each outlet of the manifold,and the manifold structure was optimized based on the air flow status inside the manifold,and the uniformity of the air flow ratio in the optimized manifold was significantly improved.
