Oscillatory Flow in Pipes of Non-Circular Cross-Section
The flow of viscoelastic liquids through pipes of circular cross-section has been recently examined for the case in which the pipe oscillates longitudinally about a mean position (1–5). The effects of amplitude and frequency of the oscillations upon the mean flow rate were evaluated and increases of an order of magnitude in the flow rate when compared to purely rectilinear flow were found.
