Micro Abstract:
Fire suppression systems operate with extinguishing agents released from a reservoir and atomized into droplets. Flow predictions are separated into the release process and the propagation of the extinguishing agent. For the latter an Euler-Lagrange approach is used to model the two-phase flow. Data of the first simulation are used for the droplet initialization. The transformation of parcels into the gaseous state is treated by a evaporation model. The propagation of the agent is investigated.
