摘要
从三维非定常守恒方程出发,采用58步化学反应模型,对瓦斯爆炸过程中火焰与压力波的伴生关系进行了数值模拟。在此基础上,模拟了氢氧燃烧驱动的破膜过程以及破膜前后压缩波、稀疏波对火焰阵面的影响;同时也详细研究了瓦斯爆炸过程中,压力波、火焰与障碍物的相互作用;通过实验和模拟验证了数学模型和所编程序的可靠性。
The chemical reaction model of 58 equations and three dimensional unsteady conversation equations are used to simulate the pressure wave induced by flame during the methane explosion. In the basis, the course of the diaphragm bursting drived by HO combustion and the influent to flame front lead by comprised wave or sparsity wave are simulated, at the same time, the interaction among pressure wave, flame and barrier is particularly studied. The reliability for mathematics models and program is determined by experiment and simulation.
