Recently Jones (1985) presented an analysis to predict liquid circulation in a draft-tube bubble column. Agreement with experimental data was satisfactory for small diameter drafttubes but the model overpredicted at larger diameters. It was suggested that this divergence was in part due to liquid ci

โฆ Synopsis
Using a visualization technique, we observed the resonance of a water column trapped in a vertically oriented capillary tube due to acoustic excitation. The analysis of the quasi-static response suggests that the upper nonvisible meniscus followed the imposed flow by means of a sliding contact line without changing its shape. We compared the experiments with a previously developed theoretical model that addresses dissipation by assuming an axially symmetric and incompressible flow field that is spatially constant along the tube axis. Whereas the model agrees well with the measured quasi-static response, the deviations in the dynamic response reveal shortcomings of the model due to the simplified treatment of the viscous dissipation.
