Multicomponent droplet vaporization in a high temperature gas
Abstract
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 compared with the results of several gas-phase and liquid-phase models. The spherical diffusion limit model and the present simplified model are recomended 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.
