【 摘 要 】

Numerical simulation of a chemically reacting flow of an expanding gas flow consisting of carbon C and its clusters (C2-C5) is presented. It is shown how the chemical composition of the mixture flow changes when it expands and its temperature decreases. The temperature range in which the nonequilibrium chemical model including separate direct and inverse cluster formation reactions should be used is determined. Variations in the effective adiabatic index in the C-C5 mixture and along the nozzle axis are given.
