Supersonic flows of gas mixtures take place in a wide range of scientific and technical problems, including space applications, streams into micro channels and nanotechnology. This paper deals with technology of the deposit of supersonic nanoparticles on the substructure of electronic components. To use this technology successfully for producing electronic instruments, it is necessary to study in detail all physical processes, including the study of the gas jets properties and their interactions with the elements of the technical systems. The supersonic expansion of gas mixtures is accompanied by several simultaneous non equilibrium processes: interfusion of layers, shock waves, heat exchange with walls and etc. To investigate such complex problems it is essential to develop adequate numerical technique that implies using stable and robust numerical algorithms and calculations on fine grids by means of high performance computer systems. This paper presents a new method for simulating gas mixture flows that enables us to solve similar problems and reduce computing time. Some results of modelling on computer systems with hybrid architectures are discussed. To accurately describe flow then methods of molecular dynamics must be used. This fact limits the size of the problem that can be modelled because it requires a significant computational cost. In this paper a model combining the macroscopic approach with the methods of molecular dynamics is given.
