Dispersion of a dense effluent continuously discharged into a stream of constant velocity is considered. The Navier-Stokes equations and advection-diffusion equation for density are solved numerically for the fields of flow and density downstream from the discharge port. The numerical results appear to simulate the dispersal of effluents within a broad density range, they satisfy certain conservation requirements and approach analytical solutions of the linearized equations for effluents of low density anomaly.
