Abstract

In this paper, the process of confined combustion of a gas mixture with a molar ratio (4:1) of hydrogen to oxygen is simulated and analyzed. The formation of deflagration to detonation transition is analyzed in it, and the process under other different operating conditions is also simulated. The maximum temperature and the maximum pressure reached during the combustion process were monitored and comparatively analyzed to demonstrate that the hydroxide-oxygen molar ratio is an important influencing factor in the deflagration to detonation transition formation of hydroxide-oxygen gas mixtures. The results indicate that increasing the hydroxide molar ratio is beneficial to inhibit the generation of deflagration to detonation transition, and no instances of deflagration to detonation transition occur when the hydroxide molar ratio is about 8:1. This study provides a theoretical basis for the safe utilization of hydrogen energy.
