Transient-thermocouple-based measurements have been used to detect soot and nanoparticles in a coflowing diffusion flame of ethylene. Total particulate volume fractions are measured as a function of the radial coordinate at different axial locations and are compared with the results obtained by UV-visible absorption measurements. The good agreement between the two independent measurements demonstrates that transient-thermocouple measurement is a powerful technique to measure total particulate volume fraction and its emissivity. This technique also furnishes point measurements which, therefore, are not affected by inversion procedures.

Abstract
Transient-thermocouple-based measurements have been used to detect soot and nanoparticles in a coflowing diffusion flame of ethylene. Total particulate volume fractions are measured as a function of the radial coordinate at different axial locations and are compared with the results obtained by UV-visible absorption measurements. The good agreement between the two independent measurements demonstrates that transient-thermocouple measurement is a powerful technique to measure total particulate volume fraction and its emissivity. This technique also furnishes point measurements which, therefore, are not affected by inversion procedures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
