Steady-State and Dynamic Rheological Properties of a Mineral Oil-Based Ferrofluid

In this study, nanoparticles were suspended in L-AN32 total loss system oil. The thixotropic yield behavior and viscoelastic of ferrofluid analyzed by steady-state dynamic methods explained according to the microscopic mechanism magneto-rheology. Herschel–Bulkley (H–B) model was used fit flow curves, observed static stress greater than stress. Both values increased as magnetic field increased, corresponding shear thinning viscosity curve more significantly strength increased. amplitude scanning results show that linear region (LVE) is reached when 10%. frequency showed storage modulus with increase at first. steadily a higher range, while slowly initial stage rapidly later stage. sweep experiments, energy are enhanced decrease temperature. These findings helpful better understand magneto-rheology ferrofluids, also provide guidance for many practical applications.
