| Abstract: | 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 experi-ment 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 line... |
