Dr Fabrizio Bonatesta

Senior Lecturer in Thermofluids

Profile

Dr Bonatesta graduated with a PhD in engine research from Nottingham University, UK, and between 2006 and 2008 worked as a Research Fellow for the Engine Research Group there. Between 2008 and 2010 he worked as a Senior R&D Engineer at Eminox Ltd, in charge of the CFD function which provided support in the design and optimisation of after-treatment technologies for OEM HD diesel engines. Since 2010, Dr Bonatesta is a permanent member of academic staff at Oxford Brookes University.

Dr Bonatesta’s research work has steadily focussed on experimental and numerical modelling activities for combustion optimisation and emissions reduction in both gasoline and diesel engines. His agenda at OBU concentrates mostly on Particulate Matter mechanisms and engine-out emissions in modern GDI engines. He has acquired extensive expertise in reactive flow modelling of engine cycles using both commercial and open-source CFD software.

At OBU, Dr Bonatesta has established a prospering research group, which works in collaboration with Ford Motor Company and CD-Adapco/Siemens for the optimisation of combustion and soot modelling capabilities. Other active research collaborations include the Soot Diagnostics Suite at the University of Nottingham, UK and the Department of Aeronautical and Automotive Engineering at Loughborough University. Since December 2015, he is a Visiting Research Fellow at NUMC (Nottingham University Malaysia Campus).

Dr Bonatesta is also supporting the successful development of pan-disciplinary research activities in the area of sustainable, energy-efficient heating systems for buildings, in collaboration with OISD, the Architectural Engineering Research Group, School of Architecture, OBU. Main focus of interest has been 3D CFD modelling and optimisation of Transpired Solar Collector systems.

Dr Bonatesta has been the recipient of two Central Research Funds Awards (2013-14 and
2014-15) and two Research Excellence Awards (2015-16 and 2016-17).
