Journal of Engineering Physics and Thermophysics Aims and scope

Equilibrium states of a thermodynamic system representing a mixture of reactive products of combustion of carbon and inert gas have been calculated at assigned pressure and temperature. The possibility has been shown of the gaseous and condensed carbon phases appearing simultaneously in the products of a chemical reaction proceeding in the system when the concentration of oxygen atoms is exceeded by the concentration of carbon atoms, i.e., in the case of oxygen deficiency. Numerical investigation has been performed under the assumption that a carbon condensate is a suspension of ultrafine graphite particles. The influence of the inert gas on the shift of chemical equilibrium in the thermodynamic system in the case of oxygen deficiency has been analyzed. Conditions have been determined under which a carbon condensate appears in the reaction products and the thermodynamic system, homogeneous earlier, becomes heterogeneous.
