<h2 class="heading hide-accessible">Summary</h2>

This project aims to develop and implement fluid-structure interaction algorithms, including interface-fitted methods [1] and two-mesh methods [2] previously developed in our group. There are two potential focuses for this project:<br /> <br /> The first focus is to develop numerical methods, which involves the derivation and implementation of new techniques. The ideal candidate should be familiar with finite element methods, weak forms, and partial differential equations, specifically Navier-Stokes equation and solid mechanics equations. The implementation can be based on small benchmark problems.<br /> <br /> The second focus of this project is to implement and apply existing methods. This requires candidates who can carry out large-scale parallel simulations, such as using FreeFem++ and PETSc. Currently, we are particularly interested in two problems: simulation of biological swimmers (such as C. elegans) interacting with the surrounding viscous flow, and simulation of aortic valve interacting with surrounding tissue, as well as blood flow.<br /> <br /> For more details, please contact Dr. Yongxing Wang (scsywan@leeds.ac.uk) or Prof. Peter Jimack (p.k.jimack@leeds.ac.uk)<br /> <br /> [1] Wang Y, Jimack PK, Walkley MA, Pironneau O. 2020.

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study in the School of Computing is an IELTS of 6.5 overall with at least 6.5 in writing and 6.0 in reading, listening and speaking or equivalent. The test must be dated within two years of the start date of the course in order to be valid.
