The study investigates the field-induced shear yield stress and the off-state viscosity of selected unimodal and bimodal magnetorheological (MR) fluids. Five grades of commercially available iron powder are used to prepare unimodal MR fluids, one for each powder grade, and bimodal MR fluids, using two grades of micron-sized powder. The iron powder contains particles with a mean diameter ranging from 1 to 8 µm. The solid loading of all fluids is held to a constant value while varying the… CONTINUE READING
