摘要
应用粒子动态分析仪进行钝体稳燃器回流区湍流结构和粒子动态特性的测量。试验提供了不同粒径粒子在流场中的分布及其与速度场的关联特性，以及三维稳燃流场的湍流特征。试验结果表明，在高湍流度、流动方向急剧变化和有粒子掺混情况下，粒子动态分析仪三维激光测量系统有热线风速仪或其它传统的湍流测量仪器不可比拟的优越性。
A particle dynamic analyzer has been used for measuring the turbulence structure andthe particle dynamic performance in the recirculation zone behind the combustion stabilizer ofabluff body. The results of the measurement show the distribution of particles of differentsizes,the correlation characteristic of the particle movement with the air flow and the tur-bulence structure of the three-dimensional flow field.It is shown that under the condition ofhigh turbulence, rapid variation of flow direction and with the mixture of particles, the par-ticle dvnamic analvzer with a three-dimensional laser measuring system is superior to anyconventional turbulence measuring instruments.
