摘　　要：应用三维激光粒子动态分析仪(PDA),对分级进风燃烧室内含颗粒湍流反应流的气固两相瞬时速度场进行了实验测量。获得了各测点处颗粒相轴向与切向瞬时速度的时间序列,并得到了各测点上颗粒相轴向与切向瞬时速度的概率密度函数(PDF)。The Three-Dimension Laser Particle Dynamic Analyzer（PDA） was utilized in the present study.The instantaneous gas and particle velocities were measured for the particle-laden turbulent reacting flow in a combustor with staged air injection.The time series of instantaneous particle axial and tangential velocities are obtained at each measuring location.The Probability Density Functions（PDF） for the instantaneous particle axial and tangential velocities are also obtained at each measuring location.
