池火热辐射计算模型对比研究

he basic characteristics of the pool fire and propagation of the thermal radiation were studied. The essay studied the characteristics of the pool fire and introduced two calculation models of the thermal radiation(point fire source model and Mudan model). Ethanol as an example, the distance from the center of the liquid pool, the liquid pool size had an influence on the total pool fire radiation, the average surface heat flux and the thermal radiation. The results show that the results of two methods are similar when the position is close or far from the fire, at this point the two models can be used. But the differences between the two methods is relatively large when the position is medium distance from the fire, the result of Mudan calculation method is relatively conservative. By combining the two methods, we can accurately grasp the characteristics of pool fire, obtaining the rule of thermal radiation propagation and its specific data.
