Abstract

A model of a gas-dispersed laminar boundary layer (LBL) on a semiinfinite plate is proposed. Unlike the majority of published works, in which the dispersed impurity permeates through an external LBL boundary, in the present work the source of the dispersed phase is the particles entrained by a flow from a surface in the flow with a small longitudinal velocity. In the LBL, the particles get into a region where the longitudinal velocity of the carrier-medium is large; therefore the Safman lift force is directed upwards and tends to carry them out of the LBL. As a result of increasing the dispersed impurity velocity, their concentration rapidly falls at a distance from the surface. Downward from the flow, the flux of porticles entrained from the surface decreases to zero, the LBL becomes a one-phase flow.
