Modeling of Detonation Combustion of Carbon Dust

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