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

Sequentially stretched film casting is an essential industrial process for the manufacture of thin polymer films used for a wide range of packaging, personal protective equipment, imaging, electronic devices, photovoltaic and other industrial applications. To maintain the integrity of the manufactured film while maximising the use of recycled material, it is critical that the polymer melt is filtered of all impurities. However, filters fill up through collection of the contaminants and need frequent and costly replacement, necessitating significant downtime to the production process. This project will develop novel computational tools to predict the evolving complex three-dimensional dynamics of the heated highly viscous, high-pressure flows through different filter designs. The aim is to gain a better understanding of the degradation of the filters over time and how to enhance their performance, efficiency and longevity. The research will require the development of computational models for the evolution of the filter properties over time, which will require some small-scale laboratory work and/or industrial pilot line studies for validation. You will be working closely with a leading manufacturing company, with a long history of supporting interesting and challenging fluid dynamics PhD projects at Leeds. You will be co-supervised by the School of Mechanical Engineering, School of Computing and Dupont Teijin Films, with lead supervisor Dr Mark Wilson.

<h2 class="heading hide-accessible">Full description</h2>

<p><strong>As a student on the CDT</strong> you will participate in a four year programme that combines an integrated MSc (completed over the first two years) paired with a three year PhD-level research programme. This gives you a combination of bespoke taught modules and inter-disciplinary research training.</p> <p>You will be part of a supportive cohort of research students with different academic backgrounds, all focusing on different aspects of Fluid Dynamics. During the taught aspects of your course you will receive a range of tailored seminars, lectures and practical laboratories to cover the computational, experimental and analytical aspects of Fluid Dynamics. This provides you with a strong background to the fundamentals of Fluid Dynamics. In addition you will have access to a wide range of personal development activities. Further information on the CDT is available here: <a href="javascript:void(0)"></a></p> <h3><strong>Leeds Institute for Fluid Dynamics (LIFD)</strong></h3> <p>CDT students will also benefit from membership of the Leeds Institute for Fluid Dynamics (LIFD), a cross-disciplinary research institute bringing together the expertise of over 200 researchers from 12 Schools in 4 Faculties at the University of Leeds. The institute provides a hub to facilitate world-leading research and education in fluid dynamics and to bring interdisciplinary perspectives to complex flow challenges.

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

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="">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;Fluid mechanics of polymer melt filtration&rsquo; as well as&nbsp;<a href="">Dr Mark Wilson</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.

<h2 class="heading">Funding on offer</h2>

<p>A full standard studentship consists of academic fees (&pound;4,600 in Session 2020/21), together with a maintenance grant (&pound;15,285&nbsp;in Session 2020/21) paid at standard Research Council rates. UK applicants will be eligible for a full award paying tuition fees and maintenance. European Union applicants will be eligible for an award paying tuition fees only, except in exceptional circumstances, or where residency has been established for more than 3 years prior to the start of the course.</p>
