Abstract: 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.

Key words: turbine cascade, motion behavior of particles, experimental investigation
