Abstract:
The results of an experimental study of the effect of a weak transverse constant electric field on the temperature distribution in a laminar flame of a Bunsen burner are presented. Using the method of planar laser-induced fluorescence, temperature fields in flames of pre-mixed lean methane and propane-air mixtures were obtained in the presence and absence of an external electric field. The results of visualization and evaluation of the temperature field indicate that the presence of an electric field leads to a change in the shape of the flame front and its deviation to the cathode, but does not significantly change the temperature distribution in the flame under study.
