Abstract
Consideration is made of the effect of applied magnetic fields on the rheological, magnetic and thermophysical properties of magnetorheological suspensions (MRS). In a field, the shear stress highly increases, and the thermal conductivity grows and becomes anisotropic. Also, specific features of magnetization due to the mechanical mobility of the magnetic moment media are shown. An invariant dependence of viscosity is obtained, the effects of mechanical memory and reversing of shear stresses in a rotating field are revealed. The results are presented on the development of the magnetorheological effect model, on the structuring kinetics and on the methods of controlling the flow, heat and mass transfer. The possibility is shown of the purposeful impact on turbulent flow in an immersed jet and in a channel. Also, the results are given of theoretical and experimental studies of the rheology of systems with a nonmagnetic dispersed phase, i.e. of suspensions of nonmagnetic particles in a magnetic fluid and of particles of high-temperature superconducting ceramic. In both cases, the increase of shear stress in a field can be compared with that in MRS.
