| 2 | Peristaltic transport in an elastic tube under the influence of dilating forcing amplitudes显示文摘We investigate flow through an elastic tube which is constrained to a prescribed external forcing consisting of a progressive travelling wave.Such a flow dynamics is closely related to that in the oesophageal tube.The mechanics of the tube is characterized by a relationship between transmural pressure difference and radial variation of the tube.Dimensionless radial variation,assumed to be small,is studied by perturbation techniques.Hesults demonstrate that the elasticity of the tube plays a significant role in the flow dynamics.An increment in the forcing amplitude of the inward radial force enhances pressure,time-averaged volume flow rate and hence axial and radial velocities.lt is revealed that the elastic nature of the oesophageal tube favors swallowing. | Sanjay Kumar Pandey Amirlal Singh | 2020 | International Journal of Biomathematics2020，13，4： | 0 |
