【摘要】 利用激光测速仪在自制的喷粉系统中对等直径短管内粉气两相流粉粒的出口速度进行了测定．应用实验技巧确定了管道内粉粒的加速，并且利用传感器测定了粉粒的质量流量．根据实验研究结果．对等直径管内粉气两相流的基本方程作了修正。更多还原

【Abstract】 In an experimental particle-injection equipment. the exiting particle velocity ofparticle-gas flows passing through a short duct of constant cross sectional area was measuredby a laser anemometer. The initial particle velocities in the duct was chosen to be 5 m/s.The mass fiow rate of particles was measured by the resistance strain gauge. Based on theexperimental results, the fundamental equations on particle-gas flow in the short duct withconstan crossection was modified.更多还原
