平面叶栅内固体粒子运动特性的实验研究

EXPERIMENTAL INVESTIGATION ON THE MOTION BEHAVIOR OF PARTICLES THROUGH A TURBINE CASCADE

利用ＮａｃＥ－１０型高速摄影机拍摄了流经平面叶栅的气固两相流中固体粒子的运动过程；在ＭｏｖｉｅｓＭｏｄｅｌ１００型胶片运动分析仪上对固体粒子的运动轨迹和速度进行了分析；并讨论了粒子的尺寸、初始速度的大小和方向对粒子在叶栅内运动特性的影响。

A Nac E-10 high speed camera is used to reappear the process of particles suspended in fluid flow through a turbine cascade. The trajectories and velocities of particles are analysed on the film analysor.The effect of particle size and initial velocity on the particle mo-tion behavior is discussed.
