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 developed computational frameworks with applications to advanced gaseous-fuelled propulsion systems. He also conducted postdoctoral research on modelling flash-boiling liquid fuel sprays at UCL. In 2016 he moved to Imperial College to continue his research mainly on advanced low/zero carbon propulsion systems and aerodynamics. Arash develops mathematical models and computational fluid dynamics (CFD) techniques to study compressible flows (such as under-expanded jets and hypersonic flows), multiphase flows (such as: cavitating, flash-boiling and trans/supercritical flows), and combustion. He is also contributing to the development of the next generation of low carbon internal combustion (IC) engines as part of an EPSRC funded project and in collaboration with Jaguar Land Rover (JLR).
