The Entrance Flow Pattern in the Extrusion Flow of Polymer Solutions : Simulation Using Complex Potential

The entrance flow patterns for Newtonian fluid and polymer solution are simulated by using the complex potential. The results of the simulation show the same entrance flow patterns as those obtained by the vizualization. The ratios of vortex and suction intensity are shown as a function of the Weiss...

Zusammenfassung:The entrance flow patterns for Newtonian fluid and polymer solution are simulated by using the complex potential. The results of the simulation show the same entrance flow patterns as those obtained by the vizualization. The ratios of vortex and suction intensity are shown as a function of the Weissenberg number (Nwe.) at low Reynolds numbers (NRe.) and of NRe and Nwe. at high Reynolds numbers.
