摘　　要：针对复杂结构造成气体流动紊乱的现象,以燃气燃烧器为研究对象,采用数值仿真手段计算和对比了数个不同钝体设计方案的气体流动状态。结果显示,在空气和燃气管道内合理增设钝体可以有效提升燃烧器出口位置处气体分布的均匀性,可以避免因气体紊乱造成的金属烧损和变形问题。In view of the phenomenon of gas flow disorder caused by complex structures,this paper takes gas burners as the research object and uses numerical simulation methods to calculate and compare the gas flow state of several different blunt body design schemes.The results show that,the reasonable addition of blunt bodies in air and gas pipelines can effectively improve the uniformity of gas distribution at the burner outlet position,and can avoid metal burning and deformation problems caused by gas turbulence.
