Fluid-conveying elastic-walled tubes arise in many engineering and biomechanical systems. Examples include blood flow in veins and arteries, flow in the airways, and industrial fluid transport and pumping systems.


This PhD project aims to consider such flows, with a particular emphasis on the dynamical interactions and energy transfers between the fluid flow and the material of the surrounding conduit. There are a number of possible areas for investigation, including:


  • Examining the energy budget for perturbations to a basic uniform flow, in able to better understand how different instabilities develop.

  • Attempting to bridge the gap between the different flows and instability regimes studied previously by different authors, to understand how different physical mechanisms interact in the transition between different regimes.

  • Studying and optimising non-peristalitic pumps, where a mean flow is generated along a tube by reversible squeezing of the tube walls.

  • Improving elastic models for a tube wall that is subject to a large axial tension (pre-stress), and using such models to improve flow predictions.

These problems will be investigated using a range of appropriate mathematical tools. Continuum mechanics models will be constructed for the fluid flow and wall mechanics, and use will be made of techniques including simplified ODE models, asymptotic analysis, and numerical computations.

Funding notes


This PhD project is offered on a self-funding basis. It is open to applicants with funding or those applying to funding sources.  Details of tuition fees can be found at http://www.uea.ac.uk/study/postgraduate/research-degrees/fees-and-funding.


A bench fee is also payable on top of the tuition fee to cover specialist equipment or laboratory costs required for the research.  The amount charged annually will vary considerably depending on the nature of the project and applicants should contact the primary supervisor for further information about the fee associated with the project.
