Abstract
The elastic influence of a viscoelastic liquid on the three-dimensional axisymmetric slow flow into a capillary was numerically investigated for the Maxwell model by the perturbation method. Comparing the behaviour of the three-dimensional axisymmetric flow with that of the two-dimensional plane one, it was confirmed that there was a large difference between their values of Weissenberg number at which the viscoelastic effect on flow began to appear. In addition, differences in shear and normal stress of three-dimensional axisymmetric flow were studied and compared with those of two-dimensional ones.
