Description
Summary:Results of studying the influence of periodic application of a weak electric field on diffusion combustion of gaseous hydrocarbons are presented. The main attention is paid to investigating the effect of the electric field parameters on flame stabilization. Two types of electric fields are considered: (1) with a pulsed-periodic variation of the field strength in time and a constant configuration of force lines (pulsed-periodic electric field); (2) with a change in the field configuration in time and a constant field strength (electric field with a time-varying configuration). Direct photo and video recording was used, as well as spectrozonal registration of the natural luminescence of the flame (at wavelengths of emission of excited radicals OH * and CH * ). It is shown that the region of flame stabilization (ignition point) tends to the place with the maximum strength of the electric field. The effect of the electric field with a time-varying configuration on combustion is the flame stabilization in the plane of electrodes and local intensification of combustion.
