Brownian dynamics simulation was performed for a polymeric liquid modeled as a suspension of model polymers consists of connected FENE dumbbells. Potential forces between a bead and another bead that belongs to another model polymer were introduced to simulate the effect of entanglement. Numerical simulations of simple shear flow qualitatively predicted typical rheology of polymer solutions. Moreover, the behavior of model polymers in a Poiseuille flow in a channel was computed. The present computation simulated entanglement of model polymers and predicted the distributions of bead and the length of model polymer due to the shear rate distribution in the channel.
