What is Experimental Study of Aluminum Particle Flame Evolution in Normal and Micro-gravity about?
This research addresses the flame structure of single aluminum particles burning in air with the emphasis on the transition from spherically symmetric to non-symmetric combustion regime. The unique feature of this work is that free motionless aluminum particles were produced and ignited in both normal and microgravity environments. That allowed us to observe whether the particle flame non-symmetry develops when effects of convection and buoyancy are minimized. The particles were produced using a novel micro-arc device ensuring repeatable formation and ignition of uniform metal droplets with controllable initial temperatures and velocities. For the microgravity experiments the device was modified to produce motionless metal particles that made it possible to study the flame structure unaffected by particle motion or buoyancy. Burning droplet temperature was measured in real time with a three wave-length pyrometer. The evolution of flame shape at normal and microgravity was studied using high-speed video imaging and correlated with the heterogeneous combustion processes. It was found that combustion times and temperatures are similar for normal and microgravity environments. A non-sy
