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)。
A three-dimensional laser particle dynamic analyzer (PDA) was used to experimentally measure the instantaneous velocity field of gas-solid two-phase flow in the graded inlet combustion chamber. The time series of the axial velocity and the tangential velocity of the particle phase at each measuring point were obtained, and the probability density function (PDF) of the axial velocity and the tangential velocity of the particle phase at each measuring point was obtained.
