Abstract
An analysis of the combined mechanisms of heat transfer, vaporization, ignition, and combustion of two parallel fuel droplet streams injected in a hot, oxidizing gas flow is presented. The analysis gives a qualitative understanding of the various complex phenomena involved in the vaporization and ignition of one stream of droplets followed by the propagation of the flame to a second stream and the establishment of diffusion flames surrounding each droplet stream. Some simplifications of the fluid mechanics of the flow are assumed, and the fuel droplet streams are represented as parallel droplet sheets injected at prescribed locations within the gas flow. Results are presented for three different stream arrangements as well as for two different fuel types and two different inlet droplet radii. For the various cases considered, comparisons are made in terms of droplet vaporization distances, droplet lifetimes, ignition delays, and flame propagation rates. Droplet lifetimes and ignition delays are shown to decrease as fuel volatility increases and as inlet droplet size and lateral stream spacing decrease.
