Abstract In order to fully understand the influence of needle-ring electrode configuration on the pro-perties of charged droplets in electro-spray, the software Ansoft Maxwell was taken as a tool, the diffe-rent needle-ring configurations were simulated, and the electrostatic distribution pattern can be achieved from the simulation results. Based on the simulation results, combined with the induction charging principle, we made some experiments on the influence of the electrode configuration on ato-mized droplets properties. The results show that the electric field intensity around the spray needle is the highest and decreases rapidly along the axial direction under all the spray needle-annular electrode configurations. The electric field intensity around the spray needle increases with the increase of charging voltage or the change of the relevant geometrical size of the electrode configurations. Among the electrode parameters investigated, when the spray needle length is 25 mm and the annular electrode thickness is 4 mm, the electric field intensity obtained is the highest and the induction charging effect is the best. The difference of relative position between the spray needle and the annular electrode will lead to a great difference in the direction of electric field, which will lead to different trajectories of droplets. The simulation results provide the design basis and theoretical basis for the rational configuration of electrode structure and the atomization effect of induction charged spray.
