Abstract

Employing both experimental and computational methods, this paper investigates the propagation characteristics of the explosion flame for two cases with gradually increasing and decreasing barrier ratios of continuous obstacles. Three variation gradients of barrier ratio were set in the increasing and decreasing continuous obstacle regions (i.e., 0.1, 0.2, and 0.3). Experimental results show that the flame front is less prone to inversion. With the increase in the barrier ratio of continuous obstacles, the effectiveness of the flame front in counteracting the impact of inversion can be enhanced. However, the maximum flame speed corresponds to the moment delay. Obstacles with larger initial barrier ratios will induce higher flame speed. For explosive overpressure, the accumulation and superposition of precursor waves and expansion waves during the rapid release can generate higher overpressure downstream, with the increase in barrier ratio. Lower downstream overpressure is due to the weaker pressure accumulation efficiency with the decreasing barrier ratio. Numerical simulation results visualize the distribution of the vorticity behind the obstacle, which explicitly unveils the generation and evolution of vortices in space. The underlying mechanism of how the flame was squeezed and stratified is analyzed and discussed as well.
