Abstract

The magnetorheological effect (MRE) is one of the means for directly affecting the mechanical properties of a fluid-flow medium. In this work the authors present a methodology and experimental results of an investigation based on a stationary model, wherein the suspension in a magnetic field is supposed to be a well-ordered system oriented at some angle to the direction of the transverse flow of noninteracting ellipsoidal aggregates. The regulation of the degree of dissipation of the mechanical energy (the effective viscosity) is accomplished through variation of the structure of the given MRS (elongation of the aggregates and their orientation angle) and by varying the intensity of the external magnetic field. In addition, the equilibrium aggregate dimension is regulated by means of addition of new or detachment of excessive particles at its poles.
