Dr Alexander Malakhov

Postdoctoral Research Fellow

Alexander was born in Kurchatov town, Russian Federation. He holds an Engineer-Physicist degree from Moscow Engineering Physics Institute. He previously worked for I.I. Leypunsky Institute of Physics and Power Engineering (IPPE), Obninsk, Russia where he had the position of research-engineer in laboratory of Computational Fluid Dynamics (CFD) analysis of physical-chemical processes in nuclear safety. He joined HySA Infrastructure Center in September 2018 as a PhD student and has defended PhD in Chemical Engineering in 2022. His main responsibility is CFD modelling of hydrogen release and distribution in confined environment and passive autocatalytic recombination processes for hydrogen safety.

Project description:

This project aims toward design of mitigation strategies for hydrogen safety by developing and validation CFD models of hydrogen leakage and passive autocatalytic recombiner technology.


PhD in Engineering with Chemical Engineering, North-West University, Potchefstroom, South Africa, 2022.

Engineer-Physicist, Moscow Engineering Physics Institute, Obninsk, Russia, 2013.
