Description

This report describes the assumptions and underlying physics upon which the computer fire model BRANZFIRE version 2004 is based. The software is intended for evaluating the performance and hazard associated with room fires including combustible room lining materials. It comprises a multi-room zone model fully integrated or coupled with flame spread and fire growth models applicable to room fire scenarios. In particular, it is intended to simulate ISO 9705 room corner fire tests. The fire growth models use fire property data obtained from a cone calorimeter as input. Model output includes but is not limited to: gas layer temperatures, pressure, room surface temperatures, layer height, visibility and fractional effective dose estimates.
