Experimental and numerical study of the effect of an electric field on a Bunsen-type flame

The effect of an electric field on the behavior of premixed methane-air fla mes has been studied. A candle-type flame has been observed experimentally and analyzed for its geometrical proportions under an electric field. A num erical model has been developed to explain some of the experimental observa tions. The model employs a two-dimensional cylindrical coordinate system an d assumes axial symmetry. The mass, momentum, species, and energy conservat ion equations are solved by an integrated version of the PHOENICS and CHEMK IN computer codes. It is concluded that the effect of the electric field on the name behavior is mainly due to ionic wind effects.
