In the first report, the dividing flow properties of Newtonian fluid in two-dimensional steady laminar flow were presented. In this report, the flow patterns and the enrgy losses of the viscoelastic fluid (separan solution) are shown. In the dividing flow of the separan solution, two separation zones were also observed, as in those of Newtonian fluid. However, the sizes of the separation zones of the viscoelastic fluid are smaller than those of Newtonian fluid. Also, swelling of the streamline to the main conduit or to the lateral conduit was observed, which was not observed for Newtonian fluid. The loss coefficients of the viscoelastic fluid are larger than those of Newtonian fluid. The loss coefficients for the lateral conduit increase as the cross-sectional area of the lateral conduit is reduced, but the loss coefficients for the main conduit do not change grately.
