Prof. Pavlos Aleiferis is the Head of the Thermofluids Section. Pavlos studied Mechanical Engineering with a Diploma thesis in Computational Fluid Dynamics (CFD) and obtained a Master of Science (MSc) in Thermal Power and Fluids Engineering from the University of Manchester with a dissertation in turbulence modelling (1996). He then joined Imperial College where he studied for a PhD (1997–2000) and conducted postdoctoral research in optical experimental techniques and numerical simulations applied to in-cylinder engine flows and injector nozzles in collaboration with Honda R&D and Keihin, Japan. Subsequently he moved to University College London (UCL) as a Lecturer in 2003, where he was promoted to Reader in 2011 and Professor of Thermofluids in 2015. In 2016 he was appointed as Chair in Thermofluids in Imperial’s Department of Mechanical Engineering. In 2013 he established with Jaguar Land Rover the Centre of Excellence in Spark-Ignition Engines.


Pavlos's research is in the fundamentals of turbulent multiphase flows with applications in advanced propulsion systems for low-carbon vehicles. The focus of his work is both experimental and computational using Laser-based optical diagnostics and numerical modelling. Research sponsors include the EPSRC, Jaguar Land Rover, Shell, MAHLE Powertrain, BP, Lotus, Ford, Delphi. Pavlos is on the Editorial Boards of Fuel published by Elsevier and Fuels published my MDPI. He has received prizes by the Combustion Institute (Sugden Award), the Institute of Physics, the Institution of Mechanical Engineers (Dugald Clerk Prize), the International Centre for Heat and Mass Transfer, the Society of Automotive Engineers. Current projects and research interests include:

• Sustainable fuels and their properties.

• Sprays, injectors and cavitation.

• Flash boiling, supercritical conditions.

• Hydrogen injection, underexpanded jets.

• Turbulence in engines.

• Flame growth and cyclic variations.

• Premixed compression ignition.

• Lubricant transport phenomena.

Pavlos also maintains a strong interest in F1 engines and aerodynamics.
