About this book

This open access book examines the mechanisms of composite explosion inhibition and venting protection. It focuses on the characteristics and influencing factors of methane–coal dust two-phase mixture explosions, including:

· The inhibition of methane/coal dust hybrid explosions using ultrafine water mist

· The suppression characteristics of ultrafine water mist on gas/dust two-phase mixture explosions

· The venting behavior of gas/dust two-phase explosions and the factors that influence it

In particular, this book clarifies the mechanisms behind vapor cloud explosions and the chain reactions triggered by explosion venting flames. While current research has primarily concentrated on suppressing explosions of single flammable substances using ultrafine water mist, this work emphasizes the importance of understanding flame propagation dynamics and explosion parameters under varying mist conditions. Gathering accurate experimental data is essential for revealing the inhibition mechanisms of gas/dust hybrid explosions.

The venting process involves complex coupling effects, including multiphase reactions, interphase heat and mass transfer, and turbulence, all influenced by numerous variables. Therefore, this book provides critical insights for both practical applications and the theoretical understanding of explosion inhibition and venting mechanisms.

9. Experimental Study on the Domino Effect in Explosions Caused by Vertically Distributed Methane Air Vapor Clouds
Abstract
Hemispherical polyvinyl chloride (PVC) films with a thickness of 0.05 mm and diameters of 0.2, 0.4, 0.6, 0.8 and 1.0 m were used to enclose the vapor cloud since a vapor cloud in the shape of a hemisphere has the highest explosion intensity.
