A STUDY FOR FIRE EXTENSION MECHANISM BETWEEN FLOORS IN A RESIDENTIAL BUILDING WITH NUMERICAL MODELING

주거형 빌딩의 층간 화염전이 화재해석 모델링

This study is intended for validation of numerical modeling of a residential building which is made to simulate a phenomenon of fire extension from floor to floor. A common residential building which has the area of 80m2 each floor and some combustibles were chosen for numerical modeling. The combustible models were verified through comparing results of numerical simulations and real fire tests. For computational analysis, the Fire Dynamics Simulator was used with Large Eddy Simulation model for turbulence. Consequently, fire-intensity was well predicted and flash-over of rooms were successfully estimated.
