Abstract

Abstract

Ignition energy plays an important role in combustible gas pipeline explosion.The experiments utilized sensors and the data acquisition system to determine measuring point pressures and explore pressure wave effects on the dynamic response of the thin-wall in the closed pipe. This study investigates the characteristics of the methane-air premixed gas flame propagation under different ignition-energy conditions, and carries on preliminary analyses of the dynamic strain of the thin-walled pipe. The results show that the increase of the ignition energy gives rise to the increase of explosive intensity, the maximum peak pressure and the dynamic strain of the thin-wall pipe in the whole process.In addition, there is still a good consistency between dynamic strain signals and pressure wave signals.These findings can provide a theoretical support for preventing gas explosion accidents in pipelines.
