摘要
对哈特曼装置上的粉尘粒子速度及均方根(root-mean-square,RMS)湍流速度进行了测量及研究,获得了哈特曼装置上不同位置粉尘粒子速度、RMS湍流速度随时间的变化曲线。粉尘粒子速度采用激光多谱勒测速仪进行测量。文中还对激光测速法及数据处理中RMS计算窗口的选取进行了讨论。
The particle velocity and root mean square(RMS) turbulence velocity on Hartmann bomb are measured and researched,the changing curve of particle velocity,RMS turbulence velocity at various positions are obtained.The particle velocity is measured by Laser Doppler Anemometer.The selection of RMS calculating window during laser measuring and data treating is also discussed.
