Physicomathematical modeling of suppression of gaseous detonation by chemically inert particles

Abstract

UDC 534.222A model for describing the propagation of a stationary detonation wave in a mixture of a gas with chemically inert particles has been proposed, and calculations of its structure have been carried out. The dynamics of interaction of the detonation wave with the cloud of chemically inert particles has been investigated. Cloud parameters ensuring successful suppression of detonation have been determined.

Physical and mathematical modeling of one-dimensional and two-dimensional structures of detonation waves in a silane-air mixture

“…Earlier we used the detailed kinetics models to calculate: -the DW propagation, attenuation and suppression in reactive gas mixtures with inert particles [6][7][8][9]; -geometrical limits of detonation [10][11]; -ignition delay times of reactive gas mixtures [3,6] and others. In these papers a lot of advantages of detailed kinetics models were presented.…”

About one collapse in two-phase fluid

“…A. Rakhmatulin [1] and investigated by other authors [2,3,4]. A symmetry algebra of the system (1) is the algebra of Galileo's group which consists of translations in time and space, Galiliean translations and rotations [5].…”

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.…”
