Effect of an electric field on the stabilization of a turbulent propane–air flame

The action of an external electric field on the combustion of a premixed propane–air mixture in a turbulent flow is considered. The effect of the geometrical parameters of turbulizing plates, the polarities of the applied voltage, and the diameter of a cylindrical cellular electrode on the magnitude of the flameout velocity is studied. It is shown that the highest flameout velocity is attained with the use of a smaller-diameter electrode and plates generating a large-scale turbulence. The intensities of action of the electric field on laminar and turbulent flames are compared.
