摘    要:作者利用激光多普勒测速仪(以下简称LDV)对浅ω形、深ω形和梅花形三种典型燃烧室内的流场进行了比较测试.测试结果表明:三种燃烧室内的流场相差较大,以深ω形燃烧室的切向速度最大,梅花形燃烧室内的紊流强度最大,浅ω形燃烧室内的切向速度及紊流强度最小.

关 键 词:燃烧室  切向速度  紊流强度  测试流场

Abstract:The author compared the measurements of flow field in shallow ω-shaped, deep ω-shaped and plum blossom-shaped combustion chambers using the LDV. The results showed there are quite differ- ences among the flow fields of these three chambers. The ω-shaped chamber had the highest tangential speed,the plum blossom-shaped chamber had the biggest turbulent intensity while the tangential speed and turbulent intensity of the shallow ω-shaped chamber were smallest ones.
Keywords:combustion chamber  tangential speed  turbulent intensity  measurement flow field
