MODELING OF TURBULENT FLOWS WITH A SURFACE-PLACED OBSTACLE AND A LINE SOURCE OF PASSIVE SCALAR

Abstract

Results of modeling a turbulent flow around a two-dimensional surface-placed obstacle of square cross-section have been obtained. Possibilities of algebraic and differential second-order models have been studied for the cases of a channel flow with a rib and turbulent boundary layer on a plate with a line source of passive contaminant. Scalar diffusion from the source in a flow behind a backward-facing step and in the boundary layer with the obstacle has been calculated.
