“…A quasi-detonation (QD) can be described as a detonation with a velocity noticeably less than the C-J value and an unusual structure [7,41,42]. Many studies have investigated QD propagation in obstructed tubes filled with repeated orifice plate obstacles, wherein the dimensions of the orifice diameter and spacing are comparable to the tube diameter [43][44][45][46][47][48][49][50][51]. In such configurations, the detonation essentially undergoes a series of diffraction and reflection from the obstacles and tube wall as it propagates.…”

“…Their results showed that the orifice with small holes caused the detonation quenching phenomenon. Otherwise, the presence of an obstacle in the pipeline ensured the easy and rapid development of flame acceleration from the deflagration wave to the detonation wave (Sun and Lu, 2020a;Wang et al, 2018a;Rainsford, Aulakh, and Ciccarelli, 2018;Cross and Ciccarelli, 2015;Teodorczyk, Drobniak, and Dabkowski, 2009). The reinitiation of detonation is influenced by the detonation instability, which is affected by the size of the orifice or obstruction and flow velocity.…”

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.

“…To this end, this paper investigates how the wall roughness influences the behavior of the detonation velocity and the cellular detonation structure near the limits. The majority of the previous studies on so-called "rough tubes" are based on the use of repeated orifice plate obstacles [14][15][16][17][18][19][20][21][22] where the dimensions of the orifice diameter and spacing are of the order of the tube diameter itself. Thus the roughness (as defined by the difference between the tube and the orifice diameter) is quite significant as compared to the tube diameter, i.e., d/D ~ O (1).…”
