| Abstract Scope |
Particle impact ignition is a threat to metal components operating in high-pressure oxygen environments, where small particles traveling at high velocities can strike metal surfaces and ignite. The burning particles can contact engine components, kindling to the surface and resulting in catastrophic ignition. In this work, we develop a model to predict ignition of a metal target by a burning particle, where heating is driven by two mechanisms: localized adiabatic deformation during particle impact, and heat flux from the burning particle in contact with the target surface. We develop a model to predict these contributions, and we validate the model by performing particle impact experiments at subsonic and supersonic impact velocities, with a range of oxygen pressures and target temperatures. The resulting framework predicts the conditions required for ignition of metal engine components in high-pressure oxygen and can be used to guide the safe design of ox-rich turbomachinery. |
