On a simulation of soot formation under diffusion combustion of hydrocarbon fuels

M. P. Galanin, A. V. Isaev, S. A. Konev

Abstract: An approach to mathematical modeling of soot particles formation and particles growth under diffusion combustion of hydrocarbon fuel is presented. The process is described with a chain of carbon transitions between different selected states. The stiff system of Kolmogorov ordinary differential equations (ODEs) is used to simulate the process. The solution of the system represents the probability of carbon presence in the selected states.

Keywords: hydrocarbon fuels, diffusion flame, dispersed carbon (soot), soot formation, Kolmogorov equations, stiff systems, Rosenbrock methods.
