Abstract:

Soot growth processes affect both the radiative heat transfer distribution in a fire as well as the smoke properties. While it is difficult to achieve long residence time effects in laboratory scale flames at normal gravity, it is relatively easier to produce these conditions in microgravity flames. Within a novel microgravity burner configuration used by Atreya and coworkers 2 and 3 seconds of residence time are achieved in a relatively small microgravity flame. We have performed computational and theoretical investigations of the soot growth processes within this geometry as well as investigations of the convective and radiative coupling on the total radiative transfer and burner characteristics.
