Suspension stability of a magnetorheological fluid employing high viscosity linear polysiloxane carrier fluids: a three-year study

Abstract This study investigates the long-term sedimentation stability of high-viscosity linear polysiloxane-based magnetorheological fluids (HVLP MRFs) using an automated vertical-axis inductance monitoring system (AVAIMS). While the inverse relationship between carrier fluid viscosity and sedimentation rate is theoretically established through Stokes’ law, experimental validation over multi-year timescales remains unreported, and no systematic framework exists for quantifying the relative cont
