Abstract
In order to clarify the effect of viscoelastic properties of polymer solutions on the E.O.R, the flow of viscoelastic fluids penetrating into the Newtonian fluid in the axisymmetrial undulating channel was examined numerically. The viscoelastic fluids used in calculations were the Giesekus fluids with a different property of shear viscosity. In the results of this numerical calculation, it is found that the shape of the interface between the both fluids is closely connected to the viscoelastic effect.
