Statistical mechanical description and modelling of turbulent collision of inertial particles. (English) Zbl 0964.76086
The authors consider the collision statistics in a dilute suspension of solid particles in turbulent gas. They propose a numerical procedure which allows to estimate relative contributions of turbulent transport effect and accumulation effect. Using numerical results, the authors construct empirical models of collision statistics.
