Abstract
A modified zonal model for calculating the thermodynamics of the gas in a fire has been developed. An equation for determining the flow rates of the gas-mixture and smoke at cross sections of a convective column is proposed. The results of numerical calculations of the parameters of the heat and mass transfer in a fire within an atrium with the use of the modified zonal model as well as zonal and field models are presented and discussed. Specifics of the use of zonal models for estimating the fire hazard in an atrium are considered.
