Rheometric and stability analysis of additive infused magnetorheological fluids: a comparative study.

Magnetorheological fluid (MRF) is a smart responsive fluid, when exposed to the magnetic field, reflects a noticeable transformation in fluid viscosity due to the presence of field responsive particles in the fluid. MRF has been utilized in variety of applications, which despite possess significant concerns regarding on sedimentation due to the density mismatch between the carrier fluid and the suspended magnetic particles. To improve the resistance of rapid sedimentation, this research aims to incorporate one of the component (additive/surfactants) blended into the fluid. The objective of the study focuses to determine the efficient incorporate-infused fluid for further application and sedimentation resistance. In this study, MRF is infused with siloxane, lithium, oleic acid and SDBS (Sodium Dodecyl Benzene Sulfonate) as additive and surfactants along with silicon oil as a carrier fluid. The significant repercussion parameters such as rheology behavior of the samples, temperature and particle sedimentation has been examined and interpreted. Substantially, the effective sample and performance has been comprehended with the insightful comparative results obtained.
