Overview
Fuel efficiency and reduced emissions are the main drivers in the development of all forms of modern propulsion systems. Reduction of power losses due to generated friction is the key to achieving these objectives. Friction occurs according to the prevailing regimes of lubrication as the result of a diverse range of operating conditions in propulsion systems.
To mitigate the untoward effects of friction, it is essential to have a fundamental understanding of its multi-physics nature. Physics of the problem is also multi-scale; from nano and meso-scale molecular level interactions of boundary active lubricant additives with the contacting surfaces to the bulk microscale combined viscous and boundary frictional contributions. The link between these physical length scales is crucial in the fundamental understanding of friction, leading to the development of effective methods of palliation from lubricant physical chemistry and rheology to mechanics of contacting surfaces, coatings and even laser surface texturing.
This year's Donald Julius Groen Lecture will address a multi-physics multi-scale integrated analytical-experimental approach to mitigate generated friction, particularly with respect to the internal combustion engines.

Professor Homer Rahnejat: Chair of Dynamics and Head of Dynamics Research Group, Loughborough University
Homer Rahnejat is Chair of Dynamics at Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University. He obtained his BSc in Production Engineering from Aston University in 1977, followed by MSc and DIC in Advanced Applied Mechanics from Imperial College, University of London in 1979. He obtained his PhD from Imperial College (1984) in elastohydrodynamic lubrication, sponsored by the MOD (RAE). He has worked in industry for 7 years and the university sector for 29 years. He has published in excess of 400 books, edited conference proceedings, journal papers and conference contributions. He became a chartered engineer and MIMechE in 1987 and MIOP in 2004. He has been the Editor-in-Chief of Proceedings of the Institution of Mechanical Engineers, Journal of Multi-body Dynamics since 1998, as well as guest editor of a number of special issues, including for Proc. IMechE, Journal of Engineering Tribology. He is also the editor-in-Chief of MDPI’s Lubricants. He has received in excess of £10 M research funding from the UK’s national funding bodies: EPSRC, DTI/TSB/Innovate UK, NAB as well as the European Commission; ERC and a large number of industrial concerns from the UK, Europe, USA and Japan.
