Confinement of inertial particles in viscous boundary layer of turbulent flow
DOI: 10.7868/S0370274X15010038
Abstract
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 β<βc the particles are blocked near the wall whereas at β>βc they gradually pass into bulk. Here β is elasticity coefficient and \beta_c=\exp(- \pi/\sqrt 3).
