“…In this process, at higher shear rates (shear rate greater than 200 s -1 ), the flow field dominates, whereas applied field dominates at lower shear rates. These ferrofluids showed completely non-Newtonian behaviour whereas the SPM nanoparticles-based ferrofluids (MZFE1) show the change in behaviour from non-Newtonian to Newtonian with an increase in shear rate similar to that reported in our earlier work [48,49]. Above the applied field of 0.3 T, the magnetic nanoparticles (magnetic nano-dipoles) orient completely in the field direction with long-chain formation in the fluid.…”

“…The fluid shows power law behaviour with small n-value between 0.1 and 0.04 for various magnetic fields in the range of 0-1.33 T indicating non-Newtonian behaviour with higher shear thinning [45]. The viscosity versus shear rate plot show the change from non-Newtonian to Newtonian behaviour at higher shear rates (shear rate greater than 300 s -1 ), as we described in our earlier work [48]. The fluid viscosity behaviour is accounted to only the applied magnetic field.…”

“…Bulk magneto-viscous measurements show a transition from non-Newtonian to Newtonian as shear rates are increased from 0.1 to 1000 s −1 at different magnetic fields. Magneto-viscosity exhibits a hysteresis at constant shear rates [16].…”

“…По мере уменьшения размера частиц возрастает их взаимодействие, что приводит к изменению технологических характеристик дисперсной среды [1]. Накоплен значительный теоретический и экспериментальный материал о влиянии магнитных полей на реологическое состояние магнитных жидкостей [2][3][4], дисперсных материалов, находящихся в псевдоожиженном состоянии [5][6][7], порошков магнитных материалов при сепарации, измельчении и прессовании [8][9][10]. Специфика поведения порошков на различных этапах обработки и целесообразность технологического процесса, обеспечивающего выпуск продукции с заданными конечными свойствами, во многом определяются физико-технологическими свойствами порошков [11][12][13][14][15].…”
