摘要：
We examine space and momentum probability distribution of inertial particles when they are placed in the viscous boundary sublayer of a turbulent flow. We demonstrate that at varying elasticity of the particle collisions with the wall the confinement-deconfinement transition occurs: at beta < beta (c) the particles are blocked near the wall whereas at beta > beta (c) they gradually pass into bulk. Here, beta is the elasticity coefficient and beta (c) = exp(-pi root 3).
