| Outline of Final Research Achievements |
In large buildings, evacuation tends to take much time. Flashover and subsequent spread of burning may happen during evacuation. Such a situation is not properly addressed by existing two-layer zone model of smoke transport. In this study, investigations were carried out on the subjects of algorithm of smoke transport calculation to be applicable to strong fire source, back layering smoke flow turned by wall surfaces, smoke transport in double-skin layer. As to burning behavior, study were made on a model of burning progress of a realistic object, increase of burning due to feedback effect from enclosures, measurement and modelling of fire spread over material surface.
