NUMERICAL ANALYSIS OF SCATTER OF FIREBRANDS(Fire Safety)

Abstract

Scatter of firebrands caused by a fire is numerically simulated by means of CFD (Computational Fluid Dynamics) based on a turbulent model. The results are compared with an investigation by the authors on the distribution of firebrands and spot fires due to a hotel fire occurred in Shirahama, Wakayama prefecture on November 17th 1998 by exploration and questionnaire. New Technique concerning motion of a flying firebrand is included in the model, and scatter of them can be predicted realistically in comparison with the former method by the authors.
