为有效减少煤炭生产过程中瓦斯爆炸冲击波造成的重大伤亡,建立了瓦斯爆炸数学和物理模型,采用了CFD流体动力学软件,对受限空间内瓦斯爆炸过程进行数值模拟,得到了管道内多孔介质厚度一定时,随着长度的变化,速度与长度、压力与长度等之间的关系。
In order to reduce the heavy casualties caused by the gas explosion shock wave in the process of coal production, mathematical and physical models of gas explosion were established. The CFD fluid dynamics software was used to simulate the gas explosion process in the confined space. The porous medium With a certain thickness, with the length of the change, speed and length, pressure and length of the relationship between.
