Determination of the critical size of a particle cloud necessary for suppression of gas detonation

Analysis of the influence of inert particles on the propagation of a cellular heterogeneous detonation

“…Fomin and Chen [9] developed an analytical formula for calculating the detonation cell size to study the influence of thermodynamic parameters of particles on detonation suppression. The geometric size of the particle cloud sufficient for detonation wave suppression was numerically found for an oxygen-air mixture [10]. In agreement with the experiments, the numerical investigation [10] showed that an increase in the condensed-phase concentration and a decrease in the particle size and particle material density increase the efficiency of detonation wave suppression by chemically inert particles.…”

Micro-level modeling of the detonation wave attenuation by inert particles

“…The relevance of our work is related to the problems of explosion and fire safety. It has been established that the addition of inert particles to an explosive mixture contributes to the detonation suppression [7][8][9][10][11][12][13]. Studies of the detonation waves and inert particles interaction are mainly carried out in a one-dimensional formulation and allow us to make estimates of the influence of the volume fraction, particles diameter, and their thermophysical properties on the ability to attenuate and suppress detonation.…”

Mathematical modeling of the detonation wave and inert particles interaction at the macro and micro levels

“…It has also been established that the addition of inert particles to an explosive mixture contributes to the suppression of detonation [3][4][5][6][7][8][9][10][11][12]. The interaction between detonation waves and inert particles have been studied mainly in one dimension, resulting in estimates of the effect of volume fraction, particle diameter, and their thermophysical properties on the ability to attenuate and suppress detonation.…”
