Applications and evaluation of two-line atomic LIF thermometry in sooting combustion environments

Abstract

Temperature measurements using planar laser-induced fluorescence (PLIF) are most often associated with experimental challenges. In addition, no PLIF technique is generally applicable in all kinds of environment. Especially under sooting conditions problems are prone to arise, which limits the use of these techniques. In this paper the two-line atomic fluorescence (TLAF) technique was investigated in sooting environments. Indium atoms were used as thermometry species and seeded into the combustion region.
