Motion and Collisions of Two Small Spherical Particles in a Shear Flow

摘要

The relative motion of small particles in a shear flow is considered. On the basis of the expressions for the velocity of relative motion, the motion trajectories of particles were calculated using the published data for the coefficients that enter into these equations. The critical trajectories determining the collision cross sections are obtained. The coagulation rate in the shear flow is estimated using the method of matching moments.
