Simulation of the Suppression of the Gas-Free Combustion of a Conical Sample with Heat Removal

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A numerical investigation of the propagation of a combustion wave in a conical sample of a compound in the process of its self-propagating high-temperature synthesis with heat removal from the outer boundaries of the sample has been performed on the basis of the model of the nonstationary gas-free combustion of such a compound in the two-dimensional axisymmetric approximation with regard for the heterogeneity of the structure of the compound and the dependence of the diffusion of the reagents in it on its temperature. The heat removal from the surface of the conical sample of the compound, critical for the suppression of its combustion, and the dependence of the thickness of the compound layer burnt out incompletely on the rate of heat removal from the compound and the geometric sizes of its sample were determined.
