Thermal chain model of electrorheology and magnetorheology
Three dimensional steady shear simulations of electrorheology (ER) and magnetorheology (MR) in a uniaxial field are presented and included the effects of Brownian motion. The shear thinning viscosity was observed in the absence of thermal fluctuations. The fluid stress decreased, especially at low Mason numbers, as the influence of Brownian motion increased. A microscopic chain model of the role played by thermal fluctuations on the rheology of ER and MR fluids was proposed.
