プール火災の燃焼性状と火炎構造

抄録

The flame characteristics and structure in pool fires are of current interest because of both fundamental curiosity and practical concerns related to flame size and shape, smoke production, radiant emission and fuel regression. These parameters are important in model for various types of fires. The pool fire is mainly controlled by buoyancy, so that the characteristics of pool fire such as flame height and puffing (oscillation) frequency change depending on both scale and gravitational environments. In this paper, the effects of scale in normal gravity on 1) fuel regression rate, 2) puffing frequency and 3) flame height are firstly discussed related to the buoyancy controlled flame structure. In recent years, the human activity range is expanding to varied gravity environments. A fire safety assessment must be assessed under the different gravity level to normal. So that the effect of gravity on flame behavior which varies depending on buoyancy is secondary discussed related to flow structure around the flame.
