Contact Dr Aaron Costall
Background
Dr Aaron Costall is a Chartered Mechanical Engineer (CEng MIMechE) and holds MEng and PhD degrees from the Department of Mechanical Engineering at Imperial College London. After completing his PhD, from 2007 Aaron spent five years as a Research Engineer and Senior Research Engineer with Caterpillar Inc., working in the Engine Research division based at Perkins Engines in Peterborough, UK. In 2012, Aaron moved to Mitsubishi Turbocharger and Engine Europe B.V. in the Netherlands, where he was responsible for engine-turbocharger matching process improvement. He returned to Imperial College London as a Research Fellow in 2014, becoming Lecturer in Thermofluids in 2017 and Senior Lecturer in 2020. He then moved to the University of Bath as a Reader in Advanced Automotive Propulsion Systems, before joining the Advanced Vehicle Engineering Centre (AVEC) at Cranfield University in October 2023.
Dr Costall's research background lies in engine air systems and their performance optimization over real-life duty cycles using new design and simulation methods. His research experience covers prediction of compressor surge and transient response in heavy-duty diesel engines, organic Rankine cycle turboexpanders for vehicle waste heat recovery, electric turbocharger design, twin-entry turbine modelling, and fundamental research in unsteady flow in turbocharger turbines.
Research opportunities
At Cranfield I am Senior Lecturer in Electric and H2 Automotive Propulsion Systems with research interests in hydrogen and alternatively fuelled IC engines, in particular the challenges for air and exhaust systems, turbomachinery, and related areas of thermofluids.
