Flame Behavior Formed Around a Building under Wind

Abstract

The purpose of this study is to investigate the properties of flames formed around a building under external wind. An experimental study is described using a small-scale enclosure having a prescribed fire source to investigate the behavior of flames emerging from an opening and ceiling of the enclosure at steady state conditions. The fire source in the enclosure was a propane porous gas burner and wood crib. In the experiment, the width and height of the opening, the discharge rate of propane gas supplied to the gas burner, wind velocity and direction to compartment were varied. The modeling of flame length, vertical height and angle are proposed to judge fire spread between buildings under the wind condition.
