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

Elastohydrodynamic lubrication (EHL) concerns the behaviour of a non-Newtonian lubricating fluid which acts to keep two elastically-deformable contacts apart by working against an applied load that is trying to force the contacting elements together. This scenario occurs in a wide variety of important engineering situations and so gaining a thorough understanding of EHL can lead to significant improvements in the efficiency of components such as those occuring in engines and other machinery. The importance of this is obvious in today's society where improved engine efficiency can lead to energy savings and has major positive environmental implications. The aim of this project is to investigate the direct use of nonlinear solution strategies, such as Newton's method, for this problem. To achieve maximum efficiency preconditioned inner-iterations are required for each step of the nonlinear solver. These must also achieve an optimal efficiency if the overall algorithm is to be competitive with existing solution strategies. This work builds on a long history of research in the group which has developed computational algorithms and tools that are used in industry as well as academia.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://www.leeds.ac.uk/info/130206/applying/91/applying_for_research_degrees">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &lsquo;Numerical algorithms for EHL&rsquo; as well as&nbsp;<a href="https://engineering.leeds.ac.uk/staff/189/dr_mark_walkley">Dr Mark Walkley</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<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 is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, 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. Some schools and faculties have a higher requirement.
