Ionic wind has shown promising applications in many fields, but it still encounters the challenges of low wind velocity and high discharge voltage. Here we propose a method of enhancing the velocity of ionic wind at given discharge voltages by Joule-heating the discharge electrode in a wire-grid corona discharge scheme. Ionic wind velocity is found to increase with the temperature of the discharge electrode with an enhancement by a magnitude of more than one order at low discharge voltages.
