ANALYSIS OF THE EFFICIENCY OF GAS DETONATION WAVE SUPPRESSION BY CHEMICALLY INERT MICROPARTICLES AT DIFFERENT INITIAL PRESSURES
The method of gaseous detonation wave control and suppression by chemically inert microparticles injection is considered. Parameters of a steady detonation wave and relative detonation cell size in a CH4 + 2O2 + N2 mixture with chemically inert microparticles (SiO2) are calculated. The influence of initial pressure on the efficiency of the gaseous detonation wave suppression is analyzed. Two scenarios are considered: (i) the mass fraction of condensed phase in the two-phase mixture is fixed and (ii) the absolute concentration of particles is fixed. In the first case the efficiency of DW suppression increased with increase of initial pressure. In the second case the increase of initial pressure leads to the decrease of the efficiency of DW suppression.
