Summary

The effect is calculated of a superposed sinusoidal vibration on the rate of discharge of an incompressible, isotropic, non-Newtonian fluid, which is in plane Poiseuille flow, under a constant pressure gradient, between two parallel plates. The calculations are made both when the vibration is longitudinal and when it is transverse. Calculations are also made in the case of Poiseuille flow through a straight pipe of circular cross-section, when a sinusoidal vibration, either longitudinal ar rotational, about the axis of the pipe is superposed.

Zusammenfassung

Es wird die Wirkung einer überlagerten Sinusschwingung auf den Durchsatz einer inkompressiblen, isotropen, nicht-newtonschen Flüssigkeit berechnet, die in einer ebenen Poiseuille-Strömung zwischen zwei parallelen Platten unter der Wirkung eines konstanten Druckgefälles ausfließt. Dabei werden sowohl Longitudinal- als auch Transversal-Schwingungen betrachtet. Anschließend werden analoge Rechnungen für eine Poiseuille-Strömung in einem geraden zylindrischen Rohr durchgeführt, wobei eine in bezug auf die Rohrachse entweder longitudinale oder rotatorische Sinusschwingung überlagert wird.
