A mathematical modeling is performed for the process of kinetic combustion of gaseous mixture: oxygen-hydrogen in subsonic steady flow in channel of a variable cross-sectional area using the method of setting with time. The software developed may be used later on a computational module for f complex program flows of chemically reacting gaseous mixtures. The description of the developed procedure of numerical modeling of three-dimensional turbulent air flow in rotating blades of an axial-flow compressor is given. The calculated results of flow in impellers of transonic and supersonic compressor stages of aircraft gas-turbine engines (GTE) in various operational modes by air flow are presented. The data obtained may be used for a theoretical forecasting of the degree of aerodynamic cleanness of blade passages geometry for axial-flow compressor stages of aircraft GTE. Design-technological documentation is developed, individual technological units and elements are manufactured, installation work and combined tests of the stand to investigate into process of bulk materials size-reduction by means of jets are carried out. They proved this technological process to be perspective. Experimental investigation of the process in jet-blasting devices for the size-reduction of bulk materials have shown an expediency of developing new schemes of heating the working zone of the size-reduction chamber to raise the size-reduction effectiveness and improve the finished product quality.
