회전 자기장이 가해지는 점성유체 내에 분산된 야누스 자기입자의 동적 거동

다국어 초록 (Multilingual Abstract)

We numerically investigate the dynamics of circular Janus magnetic particles suspended in a non-magnetic viscous fluid in the presence of an externally applied rotating magnetic field. A direct simulation that is based on the Finite Element Method (FEM) and a fictitious domain is employed to solve the particulate flow in the Stokes flow regime. The particles are assumed to be non-Brownian and inertialess. The dynamics of a single particle in the rotating field are found to be significantly influenced by the Mason number (the ratio between the magnetic torque and the viscous torque) and the magnetic susceptibility. The particle dynamics in multi-particle problems are affected by the initial orientation of each particle as well as the Mason number. Using several initial configurations of the particles, we discuss the motions of the Janus particles affected by above-mentioned parameters.
