Summary

This chapter considers size distributions and nonspherical particles and trajectories. Clouds of particles with sizes that vary significantly are described using effective averages. Nonspherical particles shapes are characterized along with their motion in free fall. Nonsphericity effects for drops in free fall and for bubbles in free rise are discussed via Weber number. Finally, shape deformation due to shear and due to deformation dynamics is considered for fluid particles.
