Using these results, flame conditions are quantified in comparison to other well-characteriz reactions including hydrocarbon and propellant fires. The aluminized flame is also used to measure rate of the particles.

Introduction Aluminized solid rocket propellants are widely used in a variety of civilian and military applications. The heat release associated with the aluminum com- bustion provides a key increase in the specific impulse for these motors, and much effort has gone into under- standing the influence of aluminum burning rate on proper rocket motor design. One aspect of propellant combustion that is stillnotwidely understood is an aluminized propellant flame burning in an off-design configuration such as that which would occur in an * Corresponding author.

Transporting and handling solid propellants introduces an unusual hazard in these sit uations, because propellant fires are not susceptible oxygen starvation and exhibit much higher tempera- tures than typical hydrocarbon fuel fires,the higher temperatures being associated with the aluminum ox idation. Understanding how an object, such as a haz- ardous materials container or munitions, will be af- fected when exposed to an accidental propellant fire a multiphysics problem involving coupled flow, com- bustion, and heat/mass transfer phenomena. Method that address this problem are based on propellant nu merical simulation models [1–5] and actual propellant experiments [6–8]. In the experimental work, it is ev- ident that a gas-fueled, propellant-simulating burner would greatly aid the analysis of propellant burn dy- 0010-2180/$ – see front matter 2008 The Combustion Institute.
