Abstract

The phenomena observed in experimental studies on the behavior of flames propagating across flammable liquids are summarized in this paper. Since the liquid phase phenomena have been investigated extensively and already presented in several well-known review papers, the present authors have concentrated on the gas phase phenomena. It is shown that the gas motion ahead of a propagating flame is important in the mechanisms of flame propagation across a flammable liquid. The effects of wind on the behavior of a flame propagating across a flammable liquid and the flame behavior near an obstacle on the flammable liquid surface are presented. It is pointed out that a knowledge of the detailed aerodynamic structure in the vicinity of the leading flame edge is necessary to understand the effect of wind on the behavior of a flame propagating across a flammable liquid. Also, typical examples of the gas and flame front motion predicted using an inviscid theory are presented. The results imply that the flame behavior near an obstacle on the flammable liquid surface is closely related to the gas motion ahead of the propagating flame.
