Abstract— Computer based compartment fire models can be classified as zone models or field models. A zone model is normally made up of two zones (a hot upper layer and a cooler lower layer). However, in postflashover models, a one zone model is acceptable. These assume the whole compartment is at a uniform temperature and gas concentration.
