- Identifiers
- UV absorption spectra in the 200-400 nm range and transient thermocouple measurements are used to characterize the process of nanoparticle formation and their carbonization to soot particles in slightly sooting premixed flames of ethylene; determination of the UV absorption spectra from 200 to 400 nm; based on the time evolution of the signal registered by a thermocouple inserted in rich flames; determination of UV absorption spectra and particle volume fraction; delay time, number concentration, carbonization rate, and temperature in different flame conditions; rates of the carbonization and coagulation process; presence of nanoparticles can be easily inferred by UV absorption and transient thermocouple measurements
