Abstract
Flow of viscoelastic fluid is commonly analyzed by using constitutive equations. In this paper, bead-spring-damper macro model is proposed as an alternative to analyze viscoelastic flow. The tetrahedral structure of beads, springs and dampers models a gathering of interwined polymer chains. Behavior of the bead-spring-damper structure is computed under start-up flow, stop flow and oscillatory flow conditions. Stress overshoot, stress relaxation, dynamic viscosity and dynamic modulus are investigated. The results show that the effect of elasticity appears strongly in the unsteady flow, and that the bead-spring-damper macro model can express characteristics of viscoelastic fluid consistently.
