摘　　要：本文建立了采用分级进风的旋流燃烧室实验台，实现了用三维激光粒子动态分析仪（ＰＤＡ）测最湍流旋流燃烧的热态瞬时速度场。在一次风旋流数为０．６９的工况下，衍到了燃烧室内气体时均轴向与切向速度和轴向与切向脉动速度均方根值的分布。A test facility for swirl combustor with staged air injection was fabricated and set up. The Three Dimension-Laser Particle Dynamic Analyzer (PDA) was utilized to measure the instantaneous gas velocity of the swirling turbulent reacting flow. The measurement was performed for the case of the swirl number for the priamry air jet being 0.69. The time-averaged and root mean square of fluctuating gas axial and tangential velocities are obtained.
