Heat release rate (HRR) vs. agent application rate (ARR)

The FLAIM FTS system does not expose a discrete critical flow rate parameter or directly solve HRR vs. ARR thresholds. Instead, it represents fire behaviour through scenario-based fire growth profiles that respond dynamically to user actions. Note that the fire does not continue to develop if no action is taken.

Suppression effectiveness is influenced by:

• Application rate and duration
• Nozzle pattern and technique
• User positioning relative to the fire and compartment

Under the hood, suppression is implemented as a volume-based effect driven by nozzle inputs (flow rate, pattern, and valve/gate position). If a user applies insufficient flow rate they will struggle to extinguish the fire; sufficient flow rate achieves a successful outcome. Thermal reduction is governed by parameters including cooling per unit volume, moisture accumulation, and steam generation, all interacting with a voxel-based thermal model.
