Mathematical model for calculating volumes mean parameters under kinetic combustion of a hydrocarbon- air homogenous mixture in reactive space and one dimensional model for unbalanced steady flow of a chemically re- acting gas mixture through channel are formulated Appropriate software is developed. Unbalanced flow of a methane- air mixture through channels of different geometric shapes is calculated testily having regard to kinetic combustion. Content of the flue gas after combustion of the gas mixture of kaprolactam production is determined by calculations. The principle of the operation is described and gas-dynamic processes in microflame combustion devices are analyzed. Procedure for a numerical solution of Navier-Stocs steady averaged equations for a compressible gas, an energy equa- tion and ones of the turbulence model by using the difference schematic of a higher accuracy on three-dimensional variables is given results of calculations of a three-dimensional turbulent air flow are presented for two versions of an air-intake for an aircraft turbulent engine. Obtained materials can be used in the design study of local and integrated characteristics of the gas flow though inlet devices and transition ducts of modern aircraft gas-turbulent engines. Refinement of the theory of isentropic gas processes to obtain a good agreement with an experiment having regard to a change in the coefficient of the equation of the process state is proposed. Peculiarities of fuel burning of solid fuel in flow fluidized bed are examined. Some types of bottom grates to create flow fluidized bed are given, criteria for higher efficiency of inducer-type cyclones are determined. Materials for resulting studies of processes into elements of jet grinding solid loose materials are given. Research results indicated the prospecting use of working medium injector in the form of the annular nozzle. Product Description popup.authors popup.nrat_date 2020-04-02 Close
