NUMERICAL RESULTS OF DIFFUSION COMBUSTION IN TURBULENT FLOW OF REACTING GASES

Abstract

This paper proposes a numerical solution to the problem of symmetrical methane flow
relative to the axis in infinite satellite flow and diffusion combustion. Dimensional equations
in the Mises variables of the turbulent boundary layer of the interacting gases were used to
model the object. The equations for the components of the gas mixture are reduced into one
equation by introducing the Schwab-Zeldovich function. To solve the problem in the Mises coordinates, a two-layer four-point nonlinear boundary separation scheme was used, and a second order along the longitudinal coordinate was given. The iterative process was used because of  nonlinearity of the storage & displacement equations of substations.Individual results of the numerical experiment are presented.
