Droplet area, temporal variations

Figure 4 also shows that the predicted temporal variations on the droplet surface area agree quite closely with each other, implying that...

Figure 3 shows the temporal variations of the normalized droplet surface area and the rate of droplet vaporization for the three modes of gas-phase heat and mass transfer. Surprisingly there is very little influence... 

Experimental Observations. Whereas many experiments have been performed on single-droplet vaporization (21,22), most of them are conducted under the influence of either natural and/or forced convection, which not only distorts spherical symmetry, but also produces unwanted temporally varying convective effects on the vaporization process as the droplet size diminishes. The observations on the droplet surface area variations, however, do agree qualitatively with the predicted behavior of the transient models shown in Figure 4.
