“…Considering the simulation accuracy, calculation amount and application scope, this study used the re‐normalization group (RNG) k‐ε model as the turbulence model 28,29 and used the eddy breakup (EBU), Arrhenius model, to simulate the chemical reaction of mine gas combustion in the pipe. Moreover, the chemical reaction was regarded as a single‐step reaction in the simulation 30‐32 …”

“…Wilson et al 16,17 pointed out that whether the flame can be extinguished depends not only on the distance and aperture size of the flame arrester, but also on the flame approaching speed, pressure increase and the temperature of the flame arrester. Sun et al 18 conducted an explosion suppression experiment using a mixture of ethylene, hydrogen and air, and the results showed that the explosion pressure at the front of the flame arrester decreased with the increase of porosity. By simulating different initial flame velocities, Wen 19 obtained the dynamic propagation and extinction characteristics of gas deflagration flame under slit spacing.…”

Aiming at the problem that common flame arresters can only extinguish deflagration flame, but cannot effectively extinguish detonation flame in large pipelines, this paper proposes a novel structure of detonation arrester based on heat transfer theory to improve the detonation flame extinguishing efficiency. The flame arresting element is composed of a large disk with long triangular slits and is used as the quenching part of detonation arrester in a monolithic structure. Compared with common flame arrester consists of several small fires retarding elements, the proposed monolithic structure is safer due to its integrity. In addition, this paper explores the relationship between flame extinguishing ability, detonation pressure, and temperature change. This investigation determined that the diameter of the quenching part and the parameters(length and height) of the long triangular slits were the key factors affecting the quenching characteristics, and as the diameter and porosity increase, the detonation pressure at the front of the flame arrester will decrease. Finally, the rationality and applicability of the structure are verified by simulation experiments. These preliminary conclusions are helpful to reveal the nature of the proposed structure and solve the technical problem of preventing detonation flame propagation of coal mine gas in large pipelines.

“…A study using a crimped ribbon flame arrester was conducted by several scientists, and they varied the length of the arrester (see a brief review from Wang et al, 2018b). Sun et al (2018) numerically investigated detonation wave propagation and quenching in an in-line crimped-ribbon flame arrester, offering key insights into initiation, quenching rules, and the impact of structural parameters on propagation. Moreover, the parameters used to assess the flame arrester's effectiveness are the propagation velocity of the combustion wave, shock wave pressure, reinitiation distance, and detonation cell size.…”

Natural gas is a very reactive fuel that easily causes a detonation wave, especially when the oxidizer is enriched with oxygen or pure oxygen. If the combustion wave is not controlled, a detonation wave can occur, which is dangerous for the safety of workers and industrial facilities. This study was conducted to develop a prototype of a detonation arrester to control detonation waves by using a detonation test tube with a total length of 3000 mm. The characteristics of the combustion wave were evaluated in the present study using a pressure sensor, an ion probe sensor, and a soot track record plate. Results showed that the propagation velocity of the combustion wave and the shock wave pressure increased, whereas the detonation cell size and the reinitiation distance decreased. The experiments performed were able to produce a shock wave pressure that was close to the Chapman-Jouguet pressure. The use of a detonation arrester model could reduce the shock wave pressure and the velocity of the combustion wave. At the initial pressure of the gas mixture of natural gas-oxygen of 10 kPa, the observed combustion phenomenon was deflagration. By contrast, when the initial pressure of the gas mixture of natural gas-oxygen was increased to 20 kPa, the observed combustion phenomenon was detonation quenching. Furthermore, increasing the initial pressure of the natural gas-oxygen mixture to 30 kPa or higher led to detonation wave propagation as the observed combustion phenomenon.
