8.2.2 Engineering Practice
Figures 8-1 and 8-2 illustrate typical slug and non-slug (cluster) flow of
particles in industrial pneumatic conveying [10]. From the theoretical and
experimental studies in the pneumatic conveying literature it is clear that the higher
the velocity of the gas in the vertical flow line, the more the particle velocities
approach the average velocity of the gas flow.

Figure 8-2: Schematic of dense solids phase flow known as “non-slugging” or “clusters”
[10].
