Research Areas

1. Safety of lithium ion batteries

- Analytical, experimental, and numerical studies of thermal runaway (TR) in lithium ion batteries (LIB) with particular focus on the mechanisms of TR

- Transient gas venting during TR

- TR propagation in LIB clusters and modules.

- Numerical modelling of TR induced fires

- Mitigation of TR propagation incorporating the fire effects

2. Fundamental research through model development and study of generic flow configurations

- Buoyant plumes
- Free and impinging jets
- Channel flows
- Wall effects
- Multi-phase flows
- Autoignition
- Flame acceleration
- Transition from deflagration to detonation
- Liquid cascades

Much of the above development has a primary focus on large eddy and direct numerical simulations (LES and DNS) while the group continues to use the Reynolds Averaged Navier Stokes computational fluid dynamics (CFD) approach for applications involving very large computational domain in the range of hundred meters. It is also develop point source based LES approach for meso scale simulations covering thousands of kilometres.

3. Cross cutting safety issues related to energy

- Decompression characteristics of pipelines, especially carbon dioxide (CO2) pipelines for transport captured CO2 as part of the carbon capture and storage (CCS) process
- Dispersion from high pressure CO2 release in the context of CCS
- Fire and explosion hazards on offshore platforms and process plants
- Safety issues related to transport, utilization and storage of liquefied natural gas (LNG)
- Safety issues related to the production, transport, utilisation and storage of hydrogen
- Potential re-ignition and flame acceleration related to the use of syngas in gas turbines

Examples of animated numerical predictions:

1) Evaporating cryogenic liquid hydrogen from 1 ton release with retention pit

2) Evaporating cryogenic liquid hydrogen from 1 ton release without retention pit

3) Evaporating cryogenic liquid hydrogen from 10 ton release with retention pit

4) Evaporating cryogenic liquid hydrogen from 10 ton release without retention pit

4. Cross cutting safety issues related to buildings and the environment

- Flame spread along solid surface
- Fire propagation and smoke movement in buildings, tunnels and transportation systems
- Structure response to fire and blast loading
- Coupled CFD and finite element (FE) analysis for the behaviour of glazing systems in fires
- Coupled CFD and FE analysis for building structure response to fires and wind loading
- Fire suppression with Micromist/fire sprinklers
- Fire safety of facades
