Web1 de out. de 1998 · ABSTRACT. The classical result of Smoluchowski [Z. Phys. Chem. 92, 129 (1917)] for the collision rate of monodisperse particles in a laminar shear flow is shown to be inaccurate due to the inclusion of the self-collision. In the present work we extend Smoluchowski’s result by excluding the self-collision in the counting of collision pairs. WebCollisions of Small Drops in a Turbulent Flow.

WebGravitational coagulation of particles in turbulent flow is investigated with respect to the electrostatic forces. As turbulence mixes particle trajectories at large distances, its account reduces the consideration of drawing particles together till some definite distance.
