Abstract: This paper presents the results of calculation of the detonation of a homogeneous gas suspension of ultrafine carbon particles with an oxidizer (oxygen or air) assuming chemical equilibrium in the products of detonation combustion. The influence of the mass fraction of carbon in such mixtures on the velocity of the detonation front and the main gas-dynamic parameters of combustion products was studied numerically. The calculation results correlate with available experimental data on detonation velocity in a suspension of coal particles in oxygen and air.

Keywords: explosion, detonation, chemical equilibrium, gas suspension, carbon, coal.
