Mathematical modelling of both the three-dimensional gas flow with solid particles in a short axisymmetric Laval nozzle and the process of interaction of flow with a solid-substrate surface is carried out. The spatial distribution of the parameters of the medium in the working region is obtained. Some basic regularities influencing on the efficiency of the sputtering process, the uniformity of the distribution of particles in the flow, hydraulic losses due to gas flow in the nozzle and within the free section are established.

Key words: sputtering, two-phase flow, mathematical modelling, supersonic flow, Laval’s nozzle.
