Approximation of Flow Curves of Magnetorheological Fluids
摘要
The authors have investigated, with the rotational viscometer, the rheological characteristics of magnetorheological fluids with a dispersed phase both on the basis of particles of carbonyl iron only and with additions of a ferrimagnetic oxide filler. Flow curves obtained by regression-analysis methods have been approximated by a power function with three parameters dependent on the magnetic field strength and the concentration of the dispersed phase.
