Rheological analysis of magnetite added carbonyl iron based magnetorheological fluid

The addition of additives to soft-magnetic carbonyl iron (CI)-based magnetorheological (MR) suspensions is a popular method for solving the intrinsic sedimentation problem. In this study, synthesized magnetite nanoparticles were added to a CI suspension and its enhanced MR properties were investigated using a rotational rheometer. Based on an analysis of the variance, two models were introduced to assess the yield stress and shear viscosity in...
