“…we have calculated these coefficients and it is observed that, at a given µ p , f , and f Γ decrease with r in contrast to f ⊥ , which remains roughly constant [27]. Moreover, f is always significantly larger than f ⊥ and f Γ regardless of the distance between particles.…”

“…Moreover, f is always significantly larger than f ⊥ and f Γ regardless of the distance between particles. For instance, for a MSB of magnetite beads (µ p = 12.5), and for contacting particles (r ≈ d p ), the values of these coefficients are f = 9.585, f ⊥ = 0.607 and f Γ = 1.581 [47,27]. Thus, the radial attractive component of the force predominates over the tangential and repulsive components which leads to a net attractive force even for relatively large values of α (Fig.…”

“…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].…”

“…Particle size decrease increases interparticle interaction leading to changing of particulate system technological characteristics [1]. Considerable theoretical and experimental material about influence of magnetic fields on rheological state of magnetic fluids [2][3][4] and particulate materials in fluidized state [5][6][7] was accumulated. There is a wide range of devices that fluidize particulate medium by means of hydration, aeration, ultrasonic, electrodynamic and electromagnetic effects [8][9][10][11].…”
