摘要
An analytical model for determining the particle collision rate in a turbulent flow with account for the effects of shear and the gravity force is presented. The model is tested by comparison with the results of direct numerical calculations performed for isotropic turbulence, the near-axis zone of a plane channel, a flow with uniform shear, and a binary mixture of particles with different densities.
