Outline of Final Research Achievements

In the fire safety design of buildings, the prediction of the fire properties in the building space is the basic principle. In this prediction, it is general that two types of analysis methods, a field model and a zone model, are used depending on the target space. The zone model predicts the building space by dividing it into one or two test bodies with uniform physical properties, and its prediction accuracy is inferior to that of the field model. However, due to its simplicity, the zone model is generally used for design practice, and the two-layer zone model is widely used especially for the initial fire property prediction. In this study, we developed a new two-layer zone model with higher prediction accuracy using the initial fire prediction results by field model using CFD.
