Soot particles formation process in pyrolysis of hydrocarbon fuels, highly diluted with argon, behind reflected shock waves was studied by using optical methods. The laser light extinction measurement was conducted to obtain total soot volume. Time history of soot particles temperature was estimated based on spectral dependence of monochromatic emissive powers from thermal radiation of the soot particles. The final soot particles temperature, corresponding to the final ambient temperature, varies from temperature behind the reflected shock wave, which is due to endothermic reactions of fuel decomposition and exothermic processes of soot particle formation. The experimental results show that the soot particles temperature governs the final soot yield. The homogeneous nucleation theory can explain the temperature dependence of soot particles formation qualitatively.
