Abstract

By using microphotography and sampling, the time-resolved droplet size and composition have been determined for freely-falling two-component droplets undergoing either vaporization or combustion in a hot environment. Results demonstrate that liquid-phase diffusional resistance is not as effective as previously suggested, and that this effectiveness further diminishes with increasing volatility differential of the mixture and decreasing gasification rate of the droplet. Thus the gasification mechanism of multicomponent fuel droplets is intermediate of those of batch distillation and diffusion-limited steady state. Theoretical calculations agree well with the experimental results.
