Suspensions of particles polarized by external fields (electric or magnetic), exhibiting strong long-range effects, have presently become quite popular. An important property of such media is the possibility of controlling the level of mechanical energy dissipation (effective viscosity) as a consequence of reversible structuring. In view of the fact that the shearing flow is 'layered,' we are dealing here with the motion of one such layer made up of polarized particles entrained by the carrier fluid, relative to some other layer. Since the particles have not been frozen into the layer, additional displacement relative to a viscous carrier medium becomes possible as a consequence of the interaction with the fields on the part of particles from an adjacent layer. Such self-excited motion on the part of particles may serve as an additional source of mechanical energy dissipation. The present study is devoted to the simulation, investigation of and evaluation of the role of this particular mechanism in energy conversion.
