Biomathematics Seminar: Slamming in flexible-channel flows (and other bodily noises)
23 February 2016 14:00 in CM105
The transport system in the body is dominated by flexible tubes conveying fluids. In many circumstances there can be a strong interaction between the internal flow and elastic forces in the vessel wall. These can be investigated at a fundamental level through studies of flows in flexible-walled channels of finite length, which are prone to vigorous self-excited oscillations. I will discuss recent mathematical and computational models that give insight into the physical mechanisms that initiate and sustain instabilities. Of particular interest is a near-singular slamming motion which appears to drive sustained large-amplitude oscillations.
