Problems related to modeling of the motion of discrete 
inclusions (solid particles, drops or bubbles) in flows with concentrated 
vorticity are considered. A comparative evaluation of the force factors 
in the equation of motion of a test particle is made. The results 
of numerical modeling of the motion of discrete inclusions in the 
gap between concentric rotating cylinders and a vortex flow formed 
by the liquid rotating with a constant angular velocity over a fixed 
base are discussed. The coordinates of the points of equilibrium of 
the test particle in the vortex flow are found.
