Brownian Dynamics Simulations of Molecular Configuration and the Rheology of FENE Polymer Solutions
A Finitely extensible nonlinear elastic(FENE)bead-spring model is developed for the nonlinear rheology of dilute solutions of FENE polymer molecules. Brownian dynamics simulation is used to capture the steady state and transient rheological behavior in shear flow. The simulations include examination of the effects of viscosity dependent the length of polymer molecule chain and shear rate. The results of simulation predict show that the shear viscosity value increases with the length of molecule chain increasing, and the model displays shear-thinning.
