Arash is a research associate within the Thermofluids Division of the Department of Mechanical Engineering at Imperial College London. He has a degree in Mechanical Engineering and an MSc in Automotive Engineering. Arash received his PhD in Mechanical Engineering (Computational Thermofluids) from University College London (UCL) where he worked on developing computational frameworks for studying under-expanded jets, in-cylinder mixture formation and combustion with focus on applications in advanced gaseous-fuelled direct-injection spark-ignition (DISI) internal combustion (IC) engines. He also conducted postdoctoral research at UCL where he was involved in the development of a numerical approach for modelling flash-boiling liquid fuel sprays. In 2016 he moved to Imperial College to continue his research on modelling complex fluid flows including cavitation, flash-boiling and supercritical injection. As part of an EPSRC-funded project and in close collaboration with major UK universities as well as industrial partners including Jaguar Land Rover, Ricardo and BP, he works on developing low and zero carbon propulsion systems. Arash is also interested in aerodynamics and has numerically investigated aerodynamic characteristics of various bodies from road cars to hypersonic vehicles.
