| Abstract: | Developments of numerical simulation for viscoelastic fluid flow based on constitutive equations are reviewed in this paper. Achievements of simulations of viscoelastic fluid flow employing finite element methods are introduced especially. It is obvious that appropriate readjustment for momentum equation and suitable weighting function for constitutive equation can enhance stability of numerical simulations and can obtain results of higher Weissenberg number. The ap- plications of constitutive equations and the researches of non-isothermal and three-dimensional numerical simulations are discussed. |
