Fluorescence spectroscopy turbulence

The purpose of this paper is to review the use of laser induced fluorescence spectroscopy (LIFS) for studying combustion processes. The study of such processes imposes severe constraints on diagnostic instrumentation. High velocities and temperatures are common, as well as turbulent inhomogeneities, and there is a need to make space and time resolved species concentration and temperature measurements. The development of LIFS has reached the point where it is capable of making significant contributions to experimental combustion studies.

Turbulent-flow total-consumption burners were the standard for flame emission spectroscopy for a number of years. In spite of certain deficiencies, they also can serve as sample cells for atomic fluorescence. The most common types of total-consumption burners include a built-in sample aspirator system. Figures 9-4 and 9-5 show their general constructional features. Winefordner and Staab (see footnote 2) used this type of burner for their early studies on analytical atomic fluorescence.
