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.

Thermal Science, 2021 It is well-known that the calorific value and heat transfer speed of coal are closely related to the coal quality index, and affect the explosion intensity and the maximum explosion pressure of coal dust explosion. In this paper, the pressure for different coal quality indexes is studied experimentally, and the main parameters affecting the pressure ...

IOP Conference Series: Earth and Environmental Science, 2021 Abstract Gasoline is volatile and can form a flammable gas mixture with air easily. Researches on the gas explosions still need to be developed so that more effective explosion prevention techniques and measures can be proposed. The maximum overpressure rise rate and deflagration index are two important parameters for measuring gas ...
