KINEMATICS AND DYNAMICS OF TRANSFORMATION OF ROTATIONAL MOTION OF PARTICLES IN A DISPERSE SYSTEM INTO MACROSCOPIC MOTION

An investigation has been made into the rotational motion of particles of a disperse system caused by hydrodynamic and magnetic forces and into its macroscopic manifestations. A method has been proposed for the rotation of such a system in a stationary fi eld for determining the main components of the dynamics and kinematics of transformation of particles′ rotation into their translational movement, i.e., the transfer of the angular momentum between individual particles and the disperse system on the whole. Factors have been established for an optimal impact on a disperse system by a magnetic fi eld and its rotation eff ects on the achievement of a goal: nondestructive control over the system′s structure or its modifi cation.
