Annotation | The work is devoted to the construction of a computational algorithm for the study of chemically reacting subsonic viscous flows. A multicomponent system of Navier-Stokes equations with the Low Mach numbers approximation is used to describe the flows. It is supplemented by a system of chemical kinetics equations. The algorithm for this model has been developed based on the method of splitting by physical processes. The time step is selected from the stability condition for the hyperbolic part of the system by iterating within one time step to calculate diffusion, viscosity, thermal conductivity and the dynamic component of pressure. The calculations performed on a sequence of thickening grids showed the convergence of the algorithm. |

Keywords | subsonic flow, chemically active flows, computational algorithm. |
