J. Sojka et al., Kinetic modeling of carbon suboxide thermal decomposition and formation ofsoot-like particles behind shock waves, COMB SCI T, 158, 2000, pp. 439-460
The kinetic modeling of thermal decomposition of C3O2 and formation of soot
-like solid particles behind shock waves is carried out. The transformation
of C atoms up to the cluster C-30 in the gas phase and the formation, grow
th, transfer, and coagulation of carbon solid particles are modeled with th
e help of a detailed gas phase kinetic scheme combined with a discrete Gale
rkin method. Together with the calculation of concentration profiles of sma
ll carbon clusters. precursors of solid panicles, soot-like solid particles
, and fullerene-like solid particles, the temperature dependencies on the i
nduction period, the growth rate constant, the yield, and the mean size of
carbon solid particles are obtained for a mixture of 0.33 % C3O2 in argon f
or the following experimental conditions: A pressure of 5.0 MPa and a tempe
rature range of 1200 to 2250 K. The comparison of these calculated values w
ith the experimentally measured ones is performed and the possible pathways
of transformation of C atoms from C3O2 to soot-like solid particles are an
alyzed.
