Purpose of the work: application of the obtained theoretical and experimental results to the optimization of the processses in the technological device flow passages, in the gas cleaning and gasification units, in pneumatic and hydraulic systems of the rocket and space techniques. Method applied: computational-analytic and experimental. Results obtained. Regimes and conditions of the initiation of self-excited gas-dropwise flows in cylindrical pipes are revealed computationally on the basis of the model of two-velocity two-temperature medium. As a result of a parametric analysis of characteristics of gasjet injectors with a supersonic working medium the operation conditions are found which are considered rational from the point of view of injection and energetics.Similarity criteria are obtained for non-stationary gasdynamic processes in vessels enabling to select efficient computational model. On the basis of the methods (techniques) developed earlier a computational study of the licuid-propellantlow-thrust jet engine system modernization is carried out. The procedure of computational estimate of thermophysical processes of solid domestic garbage pyrolysis in a sodium chloride melt is developed, an experimental development work on gasjet devices for mixing on a water-air installation is carried out. Application area: gasdynamic processews in technological devices of aviation and space techniques, energetics, engine building. Product Description popup.authors popup.nrat_date 2020-04-02 Close
