Abstract
The results of numerical studies of the processes of mixing, ignition and combustion during the expiration of jets of methane-air mixture in an axisymmetric channel. Numerical modeling of a turbulent subsonic nonequilibrium flow was performed within the framework of two-dimensional stationary equations of a “narrow channel” taking into account final rates of chemical kinetics within the framework of the global mechanism. The purpose of this work is to develop a numerical method for calculating the mixing, combustion, and propagation of various compositions of combustible mixtures in a cylindrical chamber, which makes it possible to conduct a computational experiment to study the processes of heat and mass transfer. The main problem of mathematical modeling of gas fuel combustion processes within the framework of the ANSYS Fluent software package is the choice of a turbulence model. In this work, the Patankar-Spaulding finite-difference method is used. The application of this method makes it possible to move from a rectilinear finite-difference grid to a modified curvilinear grid, which automatically “adjusts” to the flow area. Such a grid is especially convenient when calculating expanding free flows, since it does not require the addition of additional finite-difference grid nodes associated with the expansion of jet particles during the calculation process.
