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 itIn 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.

This open access book explores the flame resistance characteristics and underlying mechanisms that contribute to explosion protection in highly active combustible media. It focuses on the flame resistance properties of wire mesh and corrugated flame-retardant systems in gas explosions, examining:· The influence of wire mesh structural parameters on flame propagation during syngas explosions· The inhibitory effect of wire mesh on jet fires caused by explosion venting· The synergistic effects of resistance and inhibition on syngas explosions· The combined impact of additive-containing water mist and flame-retardant systems on syngas explosion suppression· The flame resistance characteristics of corrugated flame-retardant systems in hydrogen–methane explosions, including factors affecting flame propagation, explosion pressure, and flame temperatureNotably, this book clarifies the quenching performance and multi-factor influence patterns of hydrogen crimped-ribbon flame arresters using response surface methodology. Due to the complexity of fluid dynamics involved, revealing the changes in explosion resistance behavior and impact patterns presents a significant challenge.Understanding the morphological transformation of high-temperature flames and the pressure variation at the front and rear ends—affected by flame-retardant systems—offers theoretical support for uncovering the attenuation laws and explosion resistance mechanisms resulting from the coupling of flame and pressure waves within the narrow channels of corrugated flame arresters.The significance of this book lies in its contribution to the theoretical foundation for developing computational models of explosion resistance parameters in hydrogen-related flame-retardant systems under the influence of multiple factors.
