Biography
Jennifer Wen graduated from Shanghai Jiao Tong University in 1984. She holds a personal chair in Energy and Environment at University of Surrey in the UK, where she leads the Fire and Explosion Modelling Group. Prior to that, Jennifer held positions in Computational Dynamics Ltd. (The original vendor and developer of STAR-CD), British gas, Kingston University London and University of Warwick.
Jennifer is a Fellow of the Royal Academy of Engineering, Chair of the Explosion Liaison Group (ELG), and Vice-Chair of the International Association for Fire Safety Science (IAFSS). She sits on the Board of Directors for the International Association for Hydrogen Safety (HySAFE). Jennifer is also a Fellow of the Combustion Institute and an Associate Editor for the Proceedings of the Combustion Institute. She is a member and sub-task leader of the European Safety Panel on Hydrogen Safety (EHSP) established by the Fuel Cell and Hydrogen Joint Undertaking of the European Commission.
Jennifer's research is focused on numerical studies of reactive and non-reactive flows related to critical safety issues in the emerging energy technologies, including but not limited to:
-Hydrogen safety: accidental releases, spontaneous ignition, fire and explosions and the effect of fire attacks on hydrogen storage tanks.
-Batteries: thermal runaway of lithium-ion batteries due to thermal, mechanical or electrical abuse and its propagation in modules/packs; mitigation measures to enhance safety.
-Carbon capture and storage (CCS): safety related to pipeline transmission of the captured CO2, covering CO2 decompression in the event of pipeline rupture and its atmospheric dispersion.
-Fire modelling: a wide range of fire scenarios.
-Explosion: flame acceleration and deflagration to detonation transition.
-Safety of ammonia, especially during transportation at sea and as a fuel for gas turbines.
Abstract
The presentation will start with an overview of the research activities of my team, covering fundamental studies of flame spread and various fire scenarios, hydrogen safety, safety issues related to lithium-ion batteries (LIB), pipeline transmission of the captured carbon dioxide (CO2) in carbon capture and storage (CCS) systems as well as ammonia, especially during transportation at sea and as a fuel for gas turbines.
Hydrogen is a clean and sustainable energy carrier that is called to play an essential role in future energy systems. Although hydrogen has been used as an industrial gas for decades, its use as an energy carrier would bring it to the proximity of untrained public. This brings additional safety concerns because there are some key differences in the properties of hydrogen and conventional hydrocarbon fuels. To bring all the benefits of hydrogen to our society, hydrogen and its technologies must be safely developed, introduced, and used across a variety of applications and sectors. The 1st part of the presentation will focus on the systematic approach my team has followed to develop, validate and apply computational fluid dynamics (CFD) models for hydrogen safety research, covering spontaneous ignition in pressurised hydrogen releases, hydrogen jet flames as well as flame acceleration and deflagration to detonation transition (DDT). These will be followed by our recent numerical studies about the multi-phase flow characteristics of under-expanded cryogenic hydrogen jets and jet flames, capturing the evolution from ignition, initial development of the flame kernel to fully developed jet flames.
The 2nd part of the presentation will report our development of more efficient CFD models for industrial scale applications and our efforts in supporting safety studies of the industrial collaborators. Snapshots will be shown from our numerical predictions for the atmospheric dispersion of large-scale liquid hydrogen releases, hydrogen explosions, DDT at industrial-scale facilities.
Finally, I will introduce the joint industry project on “Improving liquid hydrogen safety for mobile applications (HySOON)”, for which I am the co-ordinator and Scientist-in-charge.
