MODEL EXPERIMENT ON SMOKE MOVEMENT IN ATRIUM NEXT TO FIRE ROOM

Abstract

The purpose of this study is clarifying the basic characteristics of the smoke movement and opening jet plume in atrium next to fire room. Authors carried out the experiments about the fire smoke movement of fire source with 1/3 scale two rooms. The main findings are as follows. Flow rate of the opening jet plume has high correlation with the smoke layer height of atrium. And it increases as the rise distance to the smoke layer height becomes long.
