Acetone: a tracer for concentration measurements in gaseous flows by planar laser-induced fluorescence
Abstract
This paper explores the use of acetone as a suitable tracer in planar laser-induced fluorescence concentration measurements in gaseous flows. The photophysics and physical properties of acetone relevant to its use as a fluorescent marker are discussed and compared to those of alternative molecular tracers, particularly the biacetyl molecule. Finally, as a direct example, concentration images obtained in a turbulent air jet seeded alternatively with acetone and biacetyl are compared.
