| Abstract: | It has been held by the authors that flame spreading over combustive solids is a common burning phenomenon occurring in forest,industry and building fires,and it is a basic problem in fire science research.Flame spreading phenomena over combustive solids were classified briefly.Progress in study of flame spreading over combustive solids was reviewed.Experimental technologies of flame spreading over combustive solids were summarized.Modelling of the flame spreading phenomena was discussed with factors,such as environmental fluid,chemical dynamics and carburizing process,taken into account.Advantages of numerical simulation were introduced.Existing problems of flame spread over solid surfaces were pointed out,and prospects for the fundamental study were addressed. |
