Flame propagation in liquid-fuel droplet arrays at elevated pressure under microgravity.

Experiments were conducted to study the combustion behavior of a fuel droplet array under microgravity. The effect of the ambient pressure on the flame propagation was investigated. Also the fundamental characteristics such as the flame propagation velocity and its mechanism were obtained. The results show that there are three different patterns of flame propagation, which depend on the ambient pressure and droplet spacing, as follows: 1) The...
