Method used: computational-analytic and experimental. Obtained results. Mahematical models are formulated, software is developed for the calculation: nonstationary two-phase one-dimensional flows accounting for external effects and phase transitions; characteristics of gaseous jet apparatus with a supersonic warking medium taking into consideration the effect of the flow wave structure on the flow parameters in the mixing chamber; diffusive combustion of a hydrocarbon fuel jet in a wake supersonic air flow in a pipe or a Channel; nonstationary two-phase flows in vessels in a two-dimensional statement as applied to the combustion chamber parameters of the low thrust jet engine for the cases of a large volume concentration of the dispers phase. Methods are developed: for the computational estimation and experimental development of the structure of a device to equalize a jet speed profile in a channel with the aid of a distributed hydraulic resistance; computational estimation of thermophysical processes of solid household garbage pyrolysis in a natrium chloride melt. The mechanism of solid household garbage destruction in the natrium chloride melt is offered an experimental development of gaseous jet devices for mixing in a water-air installation is carried out. Regimes and conditions of the self-oscillating gas-droplet flow initiation in cylindrical pipes are revealed calculationally; for gas jet injectors with a supersonic working medium the operational regimes rational from the point of view of injection and energetics, are found; a computational grounding of modernization of the system of low thrust liquid-propellant jet engines is carried out. A laboratory test bench is created for conducting the experimental studies of the dry inertial phase separation of dust-laden gaseous flows. The efficiency of a vortex-dust-separator with an independent source of a secondary vortex flow is determined experimentally. The developed software-methodic aids are shared with the SDB "Yuzhnoye". The methods and results of the computational-and-experimental development of the gas-distributional device are given to UkrSIAP. Recommendatios on the choice of the parameters of the pyrolysis reactor and structure of the gasdynamic mixing device are given to the development engineers organization. Field of application: gasdynamic processes in technological devices of aviation-and-space techniques, energetics, engine building, chemical industry.
