Summary

This paper looks at the non-Newtonian flow between symmetric rotating bodies and it establishes the condition for a coordinate surface to coincide with a surface of constant angular velocity in the primary flow. Then using a natural coordinate system based on the primary flow the equation for the stream function, for the secondary flow, is given in a neat and compact form which is suitable for further analysis and also for numerical work.

Zusammenfassung

Die vorliegende Arbeit befasst sich mit der nicht-Newtonischen Strömung zwischen symmetrischen sich drehenden Körpern; es wird die Bedingung aufgestellt dafür, dass eine Koordinaten-Oberfläche mit einer Oberfläche konstanter Winkelgeschwindigkeit in der primären Strömung zusammenfallen soll. Wenn ein natürliches, auf der primären Strömung beruhendes Koordinaten-System verwendet wird, dann ergibt sich die Gleichung für die Stromfunktion und für die sekundäre Strömung in einer geschlossenen Form, welche für weitere Analysen und auch für numerische Methoden geeignet ist.
