| Abstract: | A laminar methane diffusion flame in a constant electric field whose direction is opposite to that of the velocity of the
gas flow from the burner nozzle is considered. The mathematical model used includes the complete system of Navier-Stokes equations
for the velocity and passive admixture concentration fields, the charge transport equation, together with the Poisson equation
for the self-consistent electric field, and the chemical kinetic equations for a thin combustion zone. The calculations show
that the flame shortens and its thickness increases in the root zone when an electric field is imposed. This effect is accompanied
by a reduction in the nitrogen oxide emission, while is consistent with the experimental data.
