Study on the effect mechanism of CO on gas explosion reaction
Gong-kuang zidonghua, 2022 At present, most of the research on gas explosion takes the mixed gas of CH4 and air as the research object, but the gas explosion in coal mine is not a separate CH4 explosion, there are often CO and other components, which have a certain effect on gas ...

On the Sensitivity of the Maximum Explosion Pressure of a Dust Deflagration to Turbulence
KONA Powder and Particle Journal, 2001 The maximum explosion pressure of a deflagration is often regarded as a thermodynamic quantity and it is believed to be insensitive to the flow conditions of the combustible mixture involved. While this is true for premixed gases, the present work demonstrates that the opposite is the case when powder-air mixtures are ignited to deflagration.
