Abstract
Characterizing reactivity of metal fuel particles combined with a solid oxidizer involves understanding ignition mechanisms and flame propagation behavior. Typically thermal equilibrium codes are used by researchers trying to quantify basic properties such as flame temperature, heat of combustion, and gas generation. These models provide a means for qualitatively comparing properties of various mixtures but lack a true representation of an actual reaction and energy generated. For this reason, several researchers have employed laboratory scale diagnostics to observe real-time reaction behaviors and quantify combustion properties. This chapter will highlight many of these diagnostic approaches and how they can be safely applied to characterize reactivity. The measurements provide information on flame propagation rate and flame temperature.
