Abstract：To study the distribution of the electric field in electrostatic spraying by corona discharge method,the electric field induced by a multi-needle electrode arranged in ring shape was calculated by simulation charge method and through running program based on matlab language.The values of the potential and electric strength as well as their distributing figures were obtained.It is found that the induced electric field is extremely uneven and field strength is affected by the structure parameters of electrode such as the diameter of the annular electrode,curvature radius of the needle electrode,voltage on the electrode,the number of the needle electrodes and the height from the centre of the annular electrode to the ground.During the transporting process of the droplets from the nozzle to target,the electric field induced by the electrode plays an important role only at the beginning.
