Multicomponent droplet vaporization in a high temperature gas

The problem of transient vaporization of a multicomponent droplet in a hot convective environment is examined. A simplified model which accounts for liquid-phase internal circulation, transient droplet diffusion, and axisymmetric gas-phase convection is obtained. The results are in close agreement with the results of a more detailed model. The present simplified model is also compared with several existing gas-phase and liquid-phase models. The spherical diffusion limit model and the present simplified model are recommended for stagnant and convective situations, respectively. Attempts have been made to compare the results of the various models with the existing experimental data. Due to large scattering in the experimental measurements, no final conclusion can be drawn based on the experimental data.
