本文基于最小点火能这一物理概念,对一封闭二维平面房间内固体可燃物的燃烧及其火焰传播进行了场模拟计算;另外,还对燃烧过程中封闭房间的玻璃窗的破碎问题作了一定的计算,所得结果定性合理。 一、问题的描述 如图1,一封闭二维平面房间,大小为2.1×2.1m~2,网格划分为22×22,小方框处 In this paper, based on the physical concept of minimum ignition energy, field simulation is performed on the combustion of solid combustibles in a closed two-dimensional planar room and the propagation of the flame. In addition, the glass windows in the closed room during the combustion process are also fractured Certain calculations, the results obtained qualitatively and rationally. First, the problem described in Figure 1, a closed two-dimensional plane room, the size of 2.1 × 2.1m ~ 2, the grid is divided into 22 × 22, small square
