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

The greatest source of energy consumption in commercial kitchens is due to cooking (35%) which consists mainly of thermal processes, the by-product of which is waste heat and effluent (CO2, CO, vapour, grease and smoke particulates). There are opportunities for the local reappropriation of the waste heat, for example dish washer and glass washer equipment, which accounts for 18% of energy consumed. Fouling of heat exchangers is a major barrier to efficacy. Filter batteries are common but reduce the heat quality and create a fan power penalty in addition to generating waste to landfill. The research depth in this project is to understand how the gas, fluid and solid phase pollutants interact with the carrier phase (air) and flow boundaries to maximise capture by exploiting the thermodynamic and fluid dynamic effects on vapour pressure and particle kinetics. The innovative step in this project is to combine both heat recovery and fouling mitigation into a single equipment package local to heat demands. The benefits of which are: the reduction in flow resistance and therefore the fan power penalty; reduced duct fouling, fire risk and cleaning cost; and the locality of heat recovery to demand in the sanitation equipment, both in terms of space and time. The research will involve: critical assessment of existing heat recovery and fouling mitigation devices across the local, adjacent and far-field industries; benchmarking against requirements; identification of key mechanisms for foulant separation and heat recovery; innovation to develop a hybrid system; optimisation of the hybrid system by physical prototyping and simulation (CFD).

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

<p>The goal of this project is to develop a heat recovery system tolerant of fouling which is packaged for deployment local to heat demand in the kitchen to reduce energy consumption, carbon emissions, and enhance the quality of the kitchen environment and wellbeing of kitchen professionals. This will be achieved by innovations on the existing heat recovery and filter technologies and integration into the extraction hood.</p> <p>There are a range of both heat recovery and fouling mitigation technologies available. None combine these two effects into a single package, and either present significant fan power penalty, are remote from heat demand, are air-air heat exchange or involve the generation of waste to landfill.</p> <p>The supervision team will be a collaboration between Mechanical Engineering and Chemical and Process Engineering which together bring the breadth and depth of experience necessary to succeed.</p>

<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 &ldquo;Heat recovery and fouling mitigation for commercial kitchens&rdquo; as well as&nbsp;<a href="https://eps.leeds.ac.uk/mechanical-engineering/staff/140/professor-harvey-thompson">Professor Harvey Thompson</a>&nbsp;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>UK/EU &ndash; Engineering &amp; Physical Sciences Research Council Studentships paying academic fees of &pound;4,600 for Session 2020/21, together with a maintenance grant of&nbsp;&pound;15,285 for&nbsp;Session 2020/21&nbsp;paid at standard Research Council rates for 3.5 years. 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. Funding is awarded on a competitive basis.</p>
