Post Doctoral Research Fellow - FAC0138-1

Brunel University London - Department of Mechanical, Aero & Civil Engineering

Applications are invited for a Post-Doctoral Research Fellowship in the field of Organic Rankine Cycle (ORC), off-grid power generation and waste heat recovery in Brunel University London. The project titled “10kWe ORC integrated free piston expander” aims to develop 10KWe free piston gas expander (FPGE) that can be integrated into a wide range of distributed power generation applications, exhaust waste heat to power and concentrated solar power systems. The 22 month project involves: System design & simulation; Component development; System integration; Lab testing & model validation. Final output will include the design & testing of an opposed free piston gas expander sub-system whose many applications are of direct relevance to the energy access needs of developing countries.

The project is funded by Innovate UK and is industry-led. The Post-Doctoral Research Fellow will be required to work as part of a team and in collaboration with industrial partners to model and test the performance of the expander as well as the overall heat-to-power system, on a suitable internal combustion engine.

The new appointment will be part of the Centre of Advanced Powertrain and Fuels (CAPF), a designated University Research Centre, at Brunel University London and one of the largest academic powertrain research centres in the UK. Over the last 20 years this Centre has established an international reputation for pioneering research into reducing the fuel consumption and pollutant emissions of the internal combustion engine. CAPF is headed by Professor Hua Zhao and is comprised of 6 permanent academic staff, three technicians and approximately 30 post-doctoral researchers and research students.

Applications are invited from highly motivated individuals with a first degree and PhD in the area of mechanical engineering and related areas. The ideal candidate will have modelling and experimental research experience in expander design and testing for waste heat recovery systems while experimental research experience of internal combustion engines is highly desirable. In addition, good analytical skills and good theoretical knowledge of fluid dynamics, thermodynamics and mathematics is required. Strong communication/interpersonal skills and an ability to work independently are essential.

Enquiries can be addressed to: Dr Apostolos Pesyridis,
