COMPBRN III — A fire hazard model for risk analysis

COMPBRN III is a deterministic fire hazard computer code designed to be used in a probabilistic analysis of fire growth in a compartment. Its primary application to date has been the assessment of fire risk in the nuclear power industry. COMPBRN III follows a quasi-static approach to simulate the process of fire growth during the pre-flashover period in an enclosure. Physical models which quantify the thermal hazard (including temperature and heat fluxes) during a compartment fire are developed. Simulations of experiments are performed to test the accuracy of the improved hot gas layer model used in this version of COMPBRN in predicting the behavior of large-scale fires.
