Abstract

The results of numerical study of the flow in a channel with an annular radial jet injected along the Coanda surface are given. To describe the flow of the gas medium, the two-dimensional axisymmetric Reynolds-averaged Navier–Stokes (RANS) equations are used in combination with equations of the semi-empirical − −ω SST turbulence model. The effect of the total pressure and the width of radial jet on the velocity and static pressure distributions is studied and changes in the local structure developed at the sub- and supercritical pressure in the jet are described.
