The article presents the processes of modeling the aerodynamic flow of air
in two burner microflame devices: 1. The burner device of the combustion chamber of
a gas turbine plant; 2. The micromodular gas burner. The aerodynamic flow is
modeled in the Comsol Multiphysics software package, which is reasonable in terms
of availability and quality. The performed analysis of microflame fuel-burning devices
revealed that the dynamic and geometric characteristics affect the aerodynamics and
velocity profiles. Different airflow rates significantly affected the intensity of the
formation of recirculation zones, which also led to an increase in pressure in the
circuit. Accordingly, the flow at different heights of the cylindrical nozzle showed that
the dimensions will affect the combustion processes and, as a result, the stabilization
and formation of nitrogen oxides.
