The work addressed the characteristic of hybrid flame deflagration behaviour including the flame velocity, pressure profile, dynamic and static pressure. Two concentrations of coal dust were introduced to the methane deflagrations, which were 10 g m−3 and 30 g m−3. The results revealed that the presence of a diluted coal dust of 10 g m−3 significantly enhanced the flame travelling distance of a 5% methane concentration, from 12.5 m to 20.5 m. Introducing a 30 g m−3 coal dust concentration also enhanced the flame travelling distance of a 5% methane concentration, from 12.5 m to the EDT (End of Detonation Tube, 28.5 m). This enhancement was associated with boosting the flame velocity and the over pressure rise. For a higher methane concentration (i.e., a 7.5% methane concentration), the flame of the methane reached the EDT. Introducing 10 g m−3 coal dust to a 7.5% methane explosion increased the flame intensity signal, from 1 V to the maximum reading value (10.2 V), and enhanced the flame velocity at the EDT by about 14 m s−1 and finally, increased the stagnation pressure at the end of the detonation tube from 1.25 bar to 4.6 bar.]]> Wed 04 Sep 2019 10:06:45 AEST ]]> Influences of the initial ignition energy on methane explosion in a flame deflagration tube https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30951 –1 to 359 m·s–1 and enhanced the flame deflagration velocity from 105 m·s–1 to 179 m·s–1.]]> Wed 04 Sep 2019 09:49:11 AEST ]]> Flame deflagration in side-on vented detonation tubes: a large scale study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34894 Wed 04 Dec 2019 09:49:10 AEDT ]]> Explosion characteristics of methane-air mixtures in a spherical vessel connected with a duct https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30929 Thu 31 Oct 2019 11:47:10 AEDT ]]> Ignition and explosion characteristics of coal dust and methane mixture under conditions pertinent to ventilation air methane abatement https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36498 Fri 22 May 2020 15:46:02 AEST ]]> Applications of machine learning to predict and evaluate the explosion of premixed methane- air mixtures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:56334 Fri 06 Sep 2024 14:25:24 AEST ]]>
