Many physiological flows (e.g. blood flow in the veins and arteries or the flow of air in the pulmonary airways) are strongly affected by the interaction between the fluid flow and the vessel wall elasticity. Experimentally, the problem is typically studied with a `Starling resistor’, a device in which fluid is driven through a finite-length, thin-walled, elastic tube which is mounted on two rigid tubes and enclosed in a pressure chamber. One of the most striking features of this system is its propensity to develop large-amplitude self-excited oscillations. Our understanding of the mechanism(s) that initiate and maintain these oscillations is still limited.
