Description
Summary:Falkovich et al derive a formula for the collision rate of small heavy particles in a turbulent flow, using a recently developed formalism for tracing random trajectories. They describe an enhancement of inertial effects by turbulence intermittency and an interplay between turbulence and gravity that determines the collision rate.
