To the Computation of Equilibrium States of Hydrocarbon Combustion Products under the Lack of Oxygen

In this paper, we propose a unified approach to the computation of equilibrium states of hydrocarbon combustion products under the lack of oxygen when both gaseous and condensed carbon phases can appear simultaneously among the components of chemical reaction. One of the principles forming the basis of the approach is that the particles of a condensed substance are “large molecules” consisting of a great number of normal molecules. To illustrate the feasibility of the formulated approach, the problem of explosion of reacting gas mixture in a volume has been numerically solved. The computations have been performed for oxy-acetylene and air-acetylene mixtures.

Mathematical Modeling of Dispersed Condensed Substance Ignition by Local Energy Source

Numerical research of heat and mass transfer processes at dispersed condensed substance ignition by metallic particle heated to high temperatures was developed. It was established the influence of “hot” particle parameters on the main integrated characteristic of process – ignition delay time.
