- Abstract
- 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.
