Abstract: The analysis of relative fluid motion by Camp and Stein, which led to their well‐known formulation of particle collision rate in flocculation, is examined using standard tools from continuum mechanics. As a result of certain ...

Abstract: The nature of hydrodynamically induced particle collisions in orthokinetic coagulation is examined. For a discrete region of fluid that is exposed to linear velocity-gradients the frequency of collisions between particles ...

Abstract: The deposition of small colloids or macromolecules in membrane pores and the subsequent irreversible fouling of the membrane is considered using a simple model for membrane fouling. As a strategy for avoiding pore fouling, ...
