摘要/Abstract

摘要： 试验研究了开孔的沙丘驻涡火焰稳定器的总压损失。结果表明，和常规Ｖ型火焰稳定器规律相反，开孔沙丘驻涡稳定器比无孔的总压损失系数增大２８％。流场分析结果证明开孔沙丘驻涡稳定器总压损失增加是由于从孔进来的气流，破坏沙丘驻涡稳定器型面形成的最佳回流区气流结构，增加了稳定器出口流场的不均匀

Abstract: The total pressure loss of barchane dune vortex flame holder with holes and without holes were investigated.The experiments showed that the total pressure loss of the barchane dune vortex flame holder is 28% greater with holes than without holes,which is quite different from that of a conventional V gutter flame holder with holes(or slot).The analyses of flow field behind the flame holder show that the flows through holes of flame holder with holes destroy the optimum flow structure of recirculation zone that is formed by a special profile of flame holder and increase the non uniform of flow field behind the flame holder
