MAGNETORHEOLOGY OF ANISOTROPIC SUSPENSIONS OF NON-BROWNIAN AGGREGATES OF NANODISPERSED PARTICLES IN MAGNETIC FLUIDS

摘要

A structure-phenomenological magnetorheological equation for the dilute suspensions of non-Brownian ellipsoidal microaggregates of nanoparticles of the dispersed phase of magnetic fluids is obtained. The magnetorheological characteristics of such suspensions in a simple shear flow in the presence of a transverse magnetic field are studied in the case of the formation of a structural anisotropy in suspensions that appears due to the stationary orientation of suspended microaggregates under the action of hydrodynamic forces and forces that act from the side of an external magnetic field.
