Radiative heat transfer processes in large fires govern
the burning rate, the flame spread rate and the
potential for fire hazards. These processes are
controlled by the detailed structure of the fire,
primarily the temperature and soot distributions. In an
attempt to characterize the radiative heat transfer,
Gore and coworkers developed an optical probing
technique [Sivathanu et al., 1991; Klassen et al.,
1992a, 1992b]. The technique utilizes a multi-line
emission and absorption probe to simultaneously measure
the temperature and soot volume fraction within a narrow
region of a fire.
