Sergey Martynov received his MSc in Technical Physics from Moscow Power Engineering Institute (Technical University) in 1998. He then worked for several years as an Engineer at the Institute of High Temperatures of the Russian Academy of Sciences in Moscow. He then studied processes in fuel injectors at the University of Brighton (UK) from which he obtained his PhD in 2005 (the thesis tile: Numerical Simulation of the Cavitation Process in Diesel Fuel Injectors). Sergey’s research interests are in the field of mathematical modelling of processes in multi-phase flows, breakup and atomisation of liquid sprays and the bubble dynamics.

Dr Martynov is currently a Research Associate and Teaching Fellow.

Research project

Title: CO2PipeHaz - Quantitative Failure Consequence Hazard Assessment for Next Generation CO2 Pipelines

Supervisor: Prof Haroun Mahgerefteh

The CO2PipeHaz project (http://www.co2pipehaz.eu) is focused on the assessment of hazards associated with an accidental rupture of a high-pressure pipeline transporting the supercritical carbon dioxide (CO2). Mathematical modelling is used to calculate
the release rate and concentration levels of CO2 in the dispersion field. In particular, the dispersion flow model requires knowledge of the transient flow at the rupture plane of the pipe. Sergey's research activities on this project cover the development of a computational model of transient discharge from a CO2 pipe. A finite volume method is used to solve the set of governing equations describing the fluid flow. The resulting outflow model accounts for the multiphase nature of the flow, thermodynamic non-equilibrium and velocity slip between the flow phases, as well as the effects of friction and heat transfer at the pipe wall. The outflow model will be validated against experimental data obtained as part of the project for the transient releases from a pressurised CO2 pipe.
