Effects of downstream system on self-excited oscillations in collapsible tubes. (English) Zbl 1419.76017
Summary: During self-excited oscillation, the effects of downstream head, resistance and inertia on the amplitude and frequency of the tube outlet pressure and flow have been studied experimentally. Different sets of resistance and head combinations could be arranged to achieve identical mean pressure-flow condition, but the unsteady pressure and flow waveforms were found to be different. In a conventional experimental set-up, the direct effect of downstream resistance could be inadvertently complicated by the indirect ones, which were caused by the associated variations of mean pressure and flow on the downstream head.
