Combustion Dynamics Of Metal Powders In Mixed Gas Flows, Amy Lee Corcoran
Theses
Predictive mechanisms for particle ignition and combustion rates are required in order to develop optimized propellant and energetic formulations using micron-sized metal powders, such as aluminum and magnesium. Most current descriptions are based on laboratory experiments performed in stationary or laminar combustion configurations using pure metals burned in single oxidizers. However, practical configurations take into account different metals, including alloys, that burn in various oxidizing environments and various flow conditions. Validity of the present descriptions for such environments has not been established. This experimental study is aimed to measure burn times for aluminum, magnesium, and mechanically alloyed Al-Mg particles burning …
