Zur Modellierung und experimentellen Untersuchung von Dehnströmungsprozessen am Beispiel von hochpolymeren Lösungen

Progress and Trends in Rheology

Abstract

By using a generalized rheological equation of Jeffrey a model for various types of elongational flow is given.

It is shown that the results of this modelling can be used as a basis for the interpretation of elongational viscosities of high-polymeric solutions obtained by experiment.

Zusammenfassung

Unter Benutzung einer verallgemeinerten Rheologischen Zustandsgleichung nach Jeffrey wird ein Modell für verschiedene Formen von Dehnströmungen erarbeitet.

Es wird gezeigt, daß Ergebnisse dieser Modellierung als Grundlage für die Auswertung von experimentell ermittelten Dehnviskositäten von hochpolymeren Lösungen dienen können.
