Theoretical Research on Temperature Distribution and Smoke Flow in Region Close to Fire Source

摘要：

Through analyzing principle formed smoke backflow layer, the key factors are educed which could influence minimum wind velocity preventing backflow of smoke. Using the related theory of combustion and heat transfer and fluid dynamics, the combustion process and mechanism of different fuel in mine is analyzed. Computation model for combustion temperature of mine fire, are erected under different combustion style and fuel. Theory model of roadway longitudinal temperature attenuation is established under unsteady heat exchange. Harmfulness of secondary disasters is analyzed, which caused by backflow of smoke.
