Interest in research, model validation, and advanced simulation methodologies
- Develop and execute CFD-based fire and explosion simulations using:
- FLACS for gas dispersion, flame acceleration, and vented/unvented deflagration analysis
- FDS for gas dispersion, fire dynamics, smoke movement, heat transfer, and plume behavior
- Model ESS/BESS fire and explosion scenarios, including:
- Battery off-gas release and dispersion
- Ignition and overpressure development
- Large-scale enclosure and outdoor fire scenarios
- Apply strong fundamentals in heat transfer (convection, conduction, radiation), fluid flow and turbulence, combustion, and fire dynamics
- Analyze simulation outputs such as:
- Temperature fields, heat fluxes, and thermal exposure
- Overpressure and impulse
- Gas concentration and visibility
- Support performance-based fire and explosion safety design (PBD) aligned with applicable codes and standards
- Interpret simulation results in the context of code intent, safety objectives, and risk reduction strategies
- Assist in defining credible worst-case and design fire/explosion scenarios
- Perform pre-processing, solver execution, and post-processing of CFD simulations
- Support verification and validation (V&V) through comparison with:
- Large-scale ESS fire test data
- Literature and experimental benchmarks
- Prepare clear, defensible technical reports for internal review and external customers
- Work under guidance of senior fire and explosion engineers while progressively taking ownership of tasks
- Collaborate with multidisciplinary teams across CFD, testing, certification, and research
