摘要：综述了黏弹流体流动数值模拟的研究进展．突出介绍近十年来有限元法在黏弹流体流动数值模拟研究中取得的成果．通过动量方程的适当变形和本构方程离散权函数的合理选择，可以显著增强数值计算的稳定性，得到较高Ｗｅｉｓｓｅｎｂｅｒｇ数下的解．同时文中对黏弹流体流动数值模拟中本构方程的应用、非等温情况和三维空间下的研究进行了介绍。
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.
