摘要：
The burning process of premixed hydrogen-oxygen gas in combustion light gas gun is quite dependent on the chemical reaction rate. This paper has established the single-zone mathematical model of hydrogen-oxygen combustion, and simulated the burning process of hydrogen-oxygen in combustion light gas gun with detailed chemical kinetic mechanisms. The computed results agree quite well with the experimental results. The effects of different chemical kinetic models on the burning process were analyzed and compared with each other, and the mole fraction changes of some chemistry species for different kinetic models during the burning process was studied respectively too. The results show that the induction time is earliest when using the single-step kinetic model, and latest when using the seven-step kinetic model, the formations of species H2O2 and OH are particularly important to the combustion of hydrogen-oxygen, the chemical kinetic mechanism has an important impact on the hydrogen-oxygen combustion in combustion light gas gun.
