In this study, an experiment was performed to investigate the dynamic characteristics of flow in a collapsible tube. The effect of initial axial strain of the tube on self-excited oscillation was studied by changing the initial stretch of a silicone rubber tube at various values of the flow rate. The frequency of oscillation and the time-dependent pressure and flow rate were measured at the upstream and the downstream location of the tube. The characteristics of the self-excited oscillation were strongly affected by the initial strain in a range of smaller flow rate and smaller initial tube stretch. Three different types of oscillation were observed in the present condition. The type of oscillation changes due to variation of the initial axial strain or the supply flow rate.
