The relationship between flame structure of liquid ethanol laminar flow diffusion micro combustion under the influence of electric field, flame dimensionless height and width, and Re number was studied through experiment and numerical simulation. The results showed that flame structure shot in experiment was similar to that of the high temperature region obtained by numerical simulation. The flame structure size of the positive electric field was larger than that of the reverse electric filed. H/d was in a linear relationship with Re, and the positive electric field H/d increased faster with Re than the reverse electric field H/d. W/d increased linearly with Re firstly, and at the later stage it varied slightly. Generally, flame core temperature increased with the increase of Re. The flame core temperature of the positive electric field was higher than that of the reverse electric field. The numerical simulation values of flame dimensionless height and width and flame core temperature were in good agreement with the experimental calculated values.
