Abstract: This work is part of a series of projects which aim to advance the understanding of soot and its formation. The key parameter of interest is the measurement of temperature in the presence of soot. The present paper reports temperature measurements using non-linear regime two-line atomic fluorescence (NTLAF). This paper demonstrates the applicability of a single set of NTLAF constants across a wide range of flame conditions. NTLAF has been shown to resolve the temperature profile across the stoichiometric envelope for hydrogen, ethylene and natural gas flames, with deviation from thermocouple measurements not exceeding 100K, and typically <30K. Measurements in flames containing soot demonstrate good capacity of NTLAF to exclude interferences which hamper most two-dimensional thermometry techniques.
