description: The purpose of the masters thesis is to develop a mathematical model ofÂ  interaction of 6 with 4 and 2 in the diffusion turbulent combustion mode when the products of the process are 2 and , based on the differential equationsÂ  of momentum, energy and substance transfer, its implementation in the software package "Ansys Fluent", calculation of fields of the parameters of the process under study in a "tunnel burner" type reactor based on the model developed and preparation of recommendations on the design of the above reactor. As a result of the work, the following results were obtained: - the mathematical model of this process has been developed and verified on the basis of available literature data; - it is shown that the k-Ï SST model is the most preferable model of turbulence for calculations in the implementation of the process under study in a "tunnel burner" type reactor; - the contours of parameters such as temperature, stream function, heat flux from the reaction zone, the depth of transformation 6, etc. have been calculated for various flow rates of components and designs of coaxial cylindrical nozzle; - it has been calculated that it is preferable to supply a mixture of 6 and 2 through the axial nozzle channel and methane through the circular channel in the reactor of tunnel burner type in order to obtain a product composition close to thermodynamically equilibrium; - based on the calculations, recommendations were prepared for the design ofÂ  equipment to conduct the process at different 6 flow rates. The results will be used in the development of an industrial reactor of the "tunnel burner" type for the processing of depleted 6 during its interaction with 4 and 2 in the combustion mode with the production of and 2 .
