The article presents the processes of modeling the aerodynamic flow of air in a micromodule
gas burner with a sudden expansion at the outlet. The aerodynamic flow is modeled in the COMSOL
MULTIPHYSICS software package, which is reasonable in terms of availability and quality. The
analysis of the micromodule gas burner revealed that the dynamic and geometric characteristics affect the aerodynamics and velocity profiles. Different air flow velocities significantly affected the intensity of the formation of recirculation zones, which led to an increase in pressure in the circuit.
Accordingly, the flow at different heights of the cylindrical nozzle has shown that the dimensions will affect the combustion processes and, as a consequence, the stabilization and formation of nitrogen oxides.
