A multi-layer-zone smoke movement simulation model was developed. The model can predict the vertical distributions of the temperature and the gas concentrations in a bouilding with multiple compartments. The basic concept of this model is to divide the volume of a compartment into an arbitrary number of horizontal lavers, in which the temperature and other physical properties are assumed to be uniform. Considering mass and enthalpy flow rates through the layer interfaces and openings and heat transfer rates for each layer, zone equations for the temperature and the species mass fractions are derived. Some results of the sample calculations are demonstrated. It is considered that the model can be a practical tool to predict the behavior of fire for designing building.
