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 ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34894 Wed 04 Dec 2019 09:49:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30952 -3 coal dust concentration boosted the flame travel distance, from 6.5 m to 28.5 m, and increased the over pressure rise profile to 0.135 bar. The over pressure rise (OPR), pressure wave velocity, flame intensity and the flame velocity were significantly boosted along the LSSD in the presence of 10 g m^-3 or 30 g m^-3 coal dust concentrations in the methane flame deflagrations. Finally, the high speed camera showed that the presence of the coal dust enhanced the turbulence in the front flame. Consequently, the pressure wave and flame velocities were both increased when a 10 g m^-3 coal dust concentration coexisted with a 9.5% methane concentration in the deflagration.]]> Tue 04 Jun 2019 13:58:16 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30950 Tue 03 Sep 2019 18:31:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30032 Sat 24 Mar 2018 07:24:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30930 Mon 01 Jul 2019 10:11:58 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36498 Fri 22 May 2020 15:46:02 AEST ]]>
