BROWNIAN DYNAMICS ANALYSIS OF CLUSTER STRUCTURES AND MAGNETIC CHARACTERISTICS OF FERROMAGNETIC PARTICLES SUBJECTED TO A SHEAR FLOW FIELD

We carried out Brownian dynamics analysis of a ferromagnetic colloidal system which is subjected to both shear flow and external magnetic fields and investigated the magnetic and rheological characteristics. The effects of the strength of magnetic field, particle interactions and shear rate on the magnetisation, the viscosity and the cluster formations are examined and discussed. The cluster structures in the ferromagnetic colloidal system and rheological characteristics of the system in both low and high shear rate regions are made clear.
