Abstract:
The flame propagation process and propagation mechanism of coal dust cloud explosion in a semi-confined space are rather complicated due to numerous influencing factors. Moreover, there exists complex interaction between flame, turbulence and pressure during the explosion process. To reveal the dynamic evolution characteristics of flame behaviors and the formation mechanism of coal dust cloud in an open tube, the open Hartmann pipe was set as the simulation object, the diffusion characteristics...     »
