Popis:	Linear shear flows with constant velocity gradients are made through a duct by putting unequal-spacing parallel rods in it. The flow characteristics of the shear flows are measured and motion of shepherical particles is investigated in the duct.Effects of the velocity gradients of linear shear flows at a high Reynolds number on lift applied on a spherical particle are investigated by photographing trajectories of a sphere falling in upward shear flows and those of particles suspending in horizontal shear flows using a high speed video system. It is made clear that lift is applied on a sphere from the higher volocity side to the lower velocity side.
