Abstract: An experimental device for testing droplet evaporation under the action of ionic wind was designed. The dynamic evaporation behaviors of evaporation rate, oscillation amplitude and oscillation frequency of deionized water droplet under different electric fields and ambient gases were investigated, and the velocity distribution of ion wind field was also measured. The results show that when the voltage is lower than the corona voltage, the electric field force can reduce the droplet evaporation rate. When the voltage is higher than the corona voltage, the formation of ion wind can strengthen the droplet evaporation. Both of the increases in voltage and gas ions mobility can augment the ionic wind speed, which intensifies the droplet oscillation and increases the droplet evaporation rate. Compared with the natural evaporation of droplet, the maximum enhancement ratio of droplet evaporation rate under the action of ion wind can reach 9.89. With the increasing of voltage, the ion wind changes from the unstable status to the stable status.
