The injection of plasma flow with dust particles into axially symmetric chamber filled with neutral gas is investigated using computer simulation. Calculations were carried out at different plasma flow velocities and dust particles sizes. As a result, the spatial distributions of the plasma and dust component parameters were obtained in the chamber at different times from the start of injection. All held calculations based on hydrodynamic approximation of plasma (without taking into account the effects of turbulence and absorption of particles on the walls of vessel) and processed by method of large particles. It is shown that large dust particles are distributed in chamber along its axis. In this case a narrow plasma jet is formed in the chamber. Dust particles of small size also extend in a radial direction, forming a wave structure. In this case, it is observed a significant expansion of the plasma jet.
