Shi-xiang Song,Yang-Fan Cheng,Yang-Fan Cheng,Xiang-rui Meng,Hong-Hao Ma,Hong-yun Dai,Jie-tong Kan,Zhaowu Shen +7 more
TL;DR: In this article, the authors studied the explosion characteristics and influential factors of hybrid CH4/coal dust explosions using a 20-L spherical explosion vessel and showed that the maximum explosion pressure and maximum rate of pressure rise increase in the initial phase and then decrease as the coal dust or CH4 concentration increases.
The generation of nearly isotropic turbulence by means of grids
TL;DR: In this article, a synthesis of experimental data with simple analyses, such as pressure losses, turbulence intensities, spectra, correlation functions and length scales, is presented, and the present results are found to agree well with other data published in the literature.

Ignition of deflagration and detonation ahead of the flame due to radiative preheating of suspended micro particles
TL;DR: In this article, a flame propagating in a gaseous combustible mixture with suspended inert solid micro particles is considered, and the effect of radiation preheating as stronger as smaller is the normal flame velocity.
Journal ArticleDOI
Impact of suspended coal dusts on methane deflagration properties in a large-scale straight duct.
TL;DR: The results revealed that the presence of the coal dust enhanced the turbulence in the front flame and the pressure wave and flame velocities were both increased when a 10gm-3 coal dust concentration coexisted with a 9.5% methane concentration in the deflagration.

Effect of turbulence intensity on flame propagation and extinction limits of methane/coal dust explosions
TL;DR: In this paper, the effect of turbulence intensity on flame propagation characteristics and extinction limits of methane/coal dust explosions is investigated by Particle Image Velocimetry, and the results reveal that the flame propagation velocity increases by 78-200%, when the u′ increases from 1.86 to 2.66 m/s.

Laminar Flamelet Concepts in Turbulent Combustion
TL;DR: In this article, it is shown that the inner structure of the flamelets is one-dimensional and time dependent, and a new coordinate transformation using the mixture fraction Z as independent variable leads to a universal description.
