Figure 16
Vapour and droplet velocities induced by liquid cascades of different densities. The highest
velocities shown in both plots (for comparison) correspond to free-fall with no air resistance. The lower
velocities correspond respectively to liquid flux densities of 100, 10, 1, 0.1 and 0.01 kg/m

Figure 17
Contours of the ratio of predicted
vapour volume fraction to the saturation
volume fraction. A value of 1.0 indicates that
the vapour is saturated. The three predictions
are for different initial droplet size distributions
using the Rosin-Rammler diameters shown.
