A Microscopic Simulation for Structure Formation in Ferrofluid in Oscillatory Shear Flow

Magnetic fluid is a compound material of colloidal liquid, consisting of a base suspension liquid, nano sized magnetic particles such as Co‐ferrite or Ba‐ferrite which have their own magnetic moment, and surfactant. In order to calculate the microstructure formation process of magnetic fluid, we used the Langevin‐type microscopic equation of motion and perform the Molecular Dinamics simulation. In the study, we consider physical force originated by the magnetic and surrounding fluid flow and torque. We were able to show the various microscopic patterns of formation process in oscillatory shear flow.
