R&D Division
Suppression System Engineering & R&D
Computational fluid dynamics modelling, novel suppression agent research, and hydraulic network optimisation for next-generation fire suppression systems.
Research Overview
The Suppression System Engineering division advances the science of fire suppression through computational modelling, empirical testing, and novel agent research. Our CFD (Computational Fluid Dynamics) capabilities model suppression agent dispersion for FM-200 (HFC-227ea), Novec 1230, and IG-541 gaseous agents, as well as high-pressure water mist droplet dynamics.
A critical research focus is the development of effective suppression strategies for lithium-ion battery thermal runaway — a rapidly emerging hazard in data centres, electric vehicle facilities, and grid-scale energy storage installations. Conventional suppression approaches are often inadequate for cascading cell failure events that generate extreme temperatures and toxic off-gassing.
Our hydraulic engineering team performs detailed network analysis and pump curve modelling per AS 2118, optimising ESFR (Early Suppression Fast Response) sprinkler designs for high-bay warehouses and pre-action deluge system response times for mission-critical facilities.
Technical Methodology
From hazard characterisation through performance optimisation.
Hazard Characterisation & Agent Selection
Detailed analysis of fire hazard profiles — fuel type, heat release rate, compartment geometry — to determine optimal suppression agent: FM-200 (HFC-227ea), Novec 1230, IG-541, or high-pressure water mist.
CFD Modelling & Agent Dispersion Simulation
Computational fluid dynamics simulations model suppression agent transport, mixing, and concentration distribution throughout protected enclosures, accounting for HVAC flows, obstructions, and leakage paths.
Hydraulic Network Analysis
Pipe network modelling, pump curve analysis, and hydraulic calculations per AS 2118 to ensure adequate flow rates, pressures, and response times across all sprinkler and deluge system branches.
Prototype Testing & Validation
Full-scale suppression agent discharge testing in controlled environments, validating CFD predictions against empirical concentration measurements and extinguishment effectiveness.
Performance Optimisation & Documentation
Iterative refinement of nozzle placement, agent quantity, and discharge timing based on test results, with comprehensive engineering documentation for regulatory submission.
