Abstract

Abstract

In order to investigate the propagation characteristics and thermal shock dynamics of multiple explosive sources gas explosion in complex roadways, numerical simulations were conducted using the Fluent software under three types of dual explosive sources arrangements in the H-type tunnel, including the same side, opposite positions, and diagonal positions. It was found that, after the two explosive sources in the tunnel were ignited simultaneously, its prodromic shock wave propagated along the unburned area of the tunnel. When the two shock waves encountered, the pressure superimposed while the impulse canceled out, and the propagation of flame was blocked by the pressure superposition area, resulting in a slowdown or reversal of the speed. Compared to the single source explosion, the dual explosive sources led to a higher pressure in specific areas such as contact lane, center of bifurcation, and sidewalls. Extreme pressure zones occur at the closed end of the roadway under same-side and diagonal arrangement conditions and at the center of the bifurcation under the opposite arrangement condition.
