The vacuum cavity was used to suppress gas explosion, and the explosion flame temperature and pressure in the pipeline were studied at different attachment positions of the vacuum cavity. The results showed that the different attachment positions of the vacuum cavity not only promoted but also inhibited the temperature and pressure of the explosion flame. The effect of the explosion suppression was better at 1.3m from the inlet; the influence of different length-width ratios of the vacuum cavity on the explosion flame and pressure was analyzed under the optimal distance and found that the effect was better when the aspect ratio was 3.
