Bead-spring macro model is proposed as a new method to analyze a viscoelastic flow, The tetrahedral structure of beads and springs models a gathering of intertwined polymer chains, and the interaction between gatherings is considered. Poiseuille flow of polymeric liquid is computed simultaneously with the behavior of the bead-spring structure, The numerical results are compared with the experimental results. The results show that the bead-spring macro model can consistently express rheological properties of polymeric liquid such as non-Newtonian viscosity and normal stress differences. Besides, the present model can easily explain the flow field and the stress tensor in terms of the macro model condition. It is found that the present model can consistently simulate a Poiseuille flow, which is a flow field with various shear rates and with walls.
