The flow of viscoelastic fluid by means of a bead-spring macro model shows non-Newtonian viscosity. The shear flow characteristics of polymer solution are investigated experimentally by using by cone-plate type viscometer. The experimental results are compared with the numerical results by using bead-spring macro model, where three types of models (conventional modeling, present modeling, present modeling + random) are employed. The value and the equation of the spring constant are discussed so that the numerical results show good agreement with the experimental results. It is found that the present modeling + random can consistently express the distribution of polymer chains and the rheological property of viscoelastic fluids.
