Mathematical Simulation of Detonation Processes in a Coal-Particle Suspension

  • Published:
Combustion, Explosion and Shock Waves Aims and scope

Abstract

A physicomathematical model is developed, which describes propagation of detonation waves in a suspension of coal-dust particles in air or oxygen within the framework of the concepts of one-velocity, two-temperature continuum mechanics. The model is verified by available experimental data on the dependence of the detonation velocity on the particle concentration, on ignition delays behind shock waves, and on characteristic times of pyrolysis and combustion processes. Stationary detonation structures are analyzed. Formation and stable propagation of stationary detonation waves are demonstrated by means of numerical simulation of shock-wave initiation. Key words: shock waves, detonation, gas suspension, coal-dust particles, mathematical simulation.
