The study of flow of gas with solid particles in a flat nozzle is performed. The parameters of flow of gas with particles of powder in the flow passage of the flat supersonic nozzle are studied, as well the parameters of interaction between the solid particles of the spray deposited material and surface of the target backing plate by means of mathematical modelling of the three-dimensional constant-property flow of the viscous compressed real gas with solid particles. During the mathematical modelling of the process of flow of gas with solid particles by using highly specialized CFX-Pre 16.2 and CFX-Solver Manager 16.2 software packages the fields of parameters in the nozzle’s flow passage and near the target backing plate are obtained.

Key words: deposition, two-phase flow, mathematical modelling, supersonic flow, flat nozzle.
