Summary
In this work a study of the actual gas-phase temperatures during carbon particle formation from different carbon precursors behind shock waves has been carried out. A pyrolysis of C3O2, CCl4, C2Cl4 and C6H6 at initial (“frozen”) temperatures behind the reflected shock wave in the range 1500 - 3000 K have been studied. A significant difference between frozen and real temperatures behind shock waves was found, which was related to the heat consumption of the precursor decomposition and the heat release during particles formation. The obtained results have shown that the real temperature dependence of particle yield in all measured mixtures does not depend on the kind and initial concentration of precursors and close to that measured in premixed flames.
