RESEARCH ON THE MOTION CHARACTERISTICS OF FIBER SUSPENSIONS IN A WEDGE-SHAPED FLOW

摘要

In this paper the motion of cylindrical particle sin a wedge-shaped flow was studied. The velocity distribution of wedge-shaped flow was simulated first, then the Euler-Lagrange model used to calculate the motion of cylindrical particles. The evolution Of particle location, velocity and orientation with time was examined. The trajectories of The particles with different particle Stokes number, rate of flow and initial particle orienta- tion were drawn. The results indicate that the Stokes number and initial orientation are Important parameters which affect the particle motion. The conclusions are helpful to the Engineering applications.
