The goal of the work – verification of rational mathematical models for calculation of thermogasdynamic flows in channels and jets taking into account phase transitions and nonequilibrium physicochemical transformations. Development of the methodology of burning process experimental tests. Research methods – calculated-analytical and experimental methods. The results: generalization of a marsh algorithm to calculate a gas flow through channels located near a viscous layer for chemically interacted gas mixture. This algorithm is made in operational variant of completed software, and an influence of burning supersonic hydrogen jet in subsonic cocurent flow in channel is researched on the algorithm’s basis. The algorithm of calculation, one-dimensional and two-dimensional programs of calculation of non-steady reacting mixture flows through channels at presence of dispersion phase and phase transitions are formulated. Research of self-ignition of non-steady reacting mixture flows through channels at presence of dispersion phase and phase transitions are made. A mathematical model and a program unit for calculation of saturated gas liquid flows taking into account changes of the sound speed due to gas components evolve and liquid gas mixture formation for complicated manifold joints taking into account local hydraulic resistance are developed. The mathematical model verification on literary data is made. Software is finished off in a part of specification of gas evolve calculation methodic at transitional gasdynamic processes in vessels. Comparison of calculations and literary data is made. Methodic of experimental researches of hydrocarbon fuel mixture burning process is developed. Turbulator variants for device of preparation the mixture of gaseous hydrocarbon fuel with air are proposed. Results of research will be used at formulation research tasks at further work stages. Application fields – gasdynamic processesin technological devices of power engineering, engine manufacturing, aerospace engineering. Product Description popup.authors popup.nrat_date 2020-04-02 Close
