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.
