Summary on Grant Application Form
The project is part of an ongoing programme to provide a rational dynamic description of the phenomena that arise when viscous fluid flows through a collapsible tube, of which there are numerous physiological examples (venous blood flow, forced expiratory airflow, urine flow in urethra and ureters, etc). We have for the first time developed a soundly-based method to calculate the large, non-axisymmetric deformation of a tube wall (using shell theory). We wish to couple this to an accurate method for computing slow viscous flow in three dimensions, and apply it to investigation (a) the collapse process over the whole range of governing parameters (b) reopening of a collapsed tube after the pressure is raised at one end, (c) peristaltic pumping of fluid along a finite collapsible tube when a wave of muscular contraction propagates along. As part of (a) we will investigate the mathematics behind the phenomenon that collapsed and ancollapsed configurations can arise at the same values of the flow rate, upstream pressure, and other governing parameters.
