    Abstract
  • Three obstacles with different levels of bending strength was selected for experimental research on the impact of hydrogen-methane mixed gas explosions in order to explore the varying environmental hazards of explosion promotion. During the experiment, the images of the flame in the explosion pipeline and the upstream and downstream pressure were collected. Through the analysis of flame images and explosion pressure data, the flow field accelerated by expanding gas after explosion generates eddy currents behind obstacles, and the flow field produces different eddy currents behind obstacles of different materials, which result in the difference of peak flame velocity of gas in the later stage and the difference of explosion overpressure in pipelines. This proves the correlation between the intensity of promoting explosions and the material of obstacles. In the experiments conducted in this paper, there is a proportional relationship between the intensity of promoting explosions and the bending strength of the obstacle. Moreover, after hydrogen was added, the reaction of the gas base was accelerated and the peak explosion pressure in the obstacle pipes of the three materials began to produce obvious differences. It can be concluded that obstacles and rough walls in the environment will affect the gas explosion effect, and the difference is caused by the characteristics of the material itself, and the difference is affected by the combustion rate of the gas itself.
