Flher-like particle suspensions are common in both na-ture and industry, but there is little work reported on it.The forces acting on the fiber - like particle in fluid arestudied in this paper, and the Magnus lift, Saffman lift,pressure gradient force, and then the dynamics modelhave been received. The numerical study of the simpleshear flow past the cylinders shows that the particles ’motion is controlled by the vortex.
Fiber-like particle suspensions are common in both nature and industry, but there is little work reported on it. The forces acting on the fiber - like particle in fluid are studied in this paper, and the Magnus lift, Saffman lift, pressure gradient force, and then the dynamics model have been received. The numerical study of the simple shear flow past the cylinders shows that the particles motion is controlled by the vortex.
