Studying the Effects of Wave Dissipation Structure and Multiple Size Diffusion Chambers on Explosion Shock Wave Propagation

Explosion chambers are crucial to the technology used prevent coal mine gas explosions. Investigating shock wave propagation law at various tunnel cross-sections helps ensure safety. A self-built, highly explosive experimental setup was conduct empirical research on straight tubes, eight sizes of single-stage explosion chambers, and multi-stage tandem chambers. Ansys Fluent numerical simulation software constructed five different chamber models. The dissipation efficiency types calculated, process waves across multiple were examined, best size type summarized increase Gun silencers inspired these findings indicate that three-stage is diffusion combination form, 60° silencer-type modification program, 500 mm × 200 chamber.
