Rheologica Acta Aims and scope Submit manuscript

Summary

The flow of simple fluids through open channels is investigated by means of perturbation method. It is shown that fluids of second grade have the same velocity distribution likeNavier-Stokes' fluids. Fluids of third grade lead to corrections of the axial velocity distribution. Secondary flow takes place only in case of fluids of fourth grade.

Zusammenfassung

Die offene Kanalströmung einfacher Flüssigkeiten ist mittels Störungsrechnung untersucht worden. Flüssigkeiten zweiten Grades zeigen dieselbe Geschwindigkeitsverteilung wie dieNavier-Stokesschen Flüssigkeiten. Flüssigkeiten dritten Grades ändern nur die axiale Geschwindigkeitsverteilung, aber Flüssigkeiten vierten Grades führen zu Sekundär-Strömungen.
