Abstract
Recently, complex fluid that forms structures inside of the fluid is paid attention. Polymer fluids, a representative example of the complex fluid, show different rheological properties from Newtonian fluid. Thus, In this research, the FENE dumbbell model was used to model a solution of polymers without side chain. The Brownian dynamics simulation of shear flows for a system of suspension of model polymers was performed to evaluate rheological properties of polymeric fuid and to analyze the configuration of polymers under shear flows. When the length of model polymer is long, both the shear viscosity and the first normal stress coefficient are large. Brownian force largely affects the rheological property and the configuration at low shear rate.
