About the Project

The PhD student will thoroughly investigate fooling in Heat pipe based heat exchangers used in industrial waste heat recovery. After building a solid theoretical background on fooling in heat exchangers, the student will aim at modelling fouling using CFD tools and comparing it to the theory. Once the doctoral researcher has gained enough experience of simulating and modelling the apparition of fouling in heat pipe heat exchangers, new designs solutions are expected to be developed to reduce the fouling phenomenon. The new designs are expected to be validated using theory, CFD simulation and Experiments.
The research will mainly focus on the gas/solid interactions and on the formation of fouling in Heat pipe based heat exchanger. The researcher will be challenged to increase his/her theoretical, design, CFD (Computational Fluid dynamics) simulation skills, and Experimental skills and publish quality articles in international conference and journals.

The student should show his interest into developing his design and CFD simulation skills while contributing to develop new environmentally-friendly solutions for heat pipe based heat exchangers. It is also expected from the student to show why this research suits him/her personal expectation and career plan.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
