Electrohydrodynamic Microfabricated Ionic Wind Pumps for Electronics Cooling Applications
… an electrohydrodynamic (EHD) corona discharge or ionic wind pump that has the potential to meet industry requirements as a next generation solution for thermal management applications. A single ionic wind pump element consists of two parallel collecting electrodes between which a single emitting …

Enhanced Ambient Heat Rejection in Passive Thermal Management Systems
… The first technology considered uses ionic wind to increase the air flow through cooling passages. Ionic wind occurs when a high voltage potential is applied to an electrode with a large curvature – typically a thin wire or a needle. Due to the strong electric potential close to the …

Electric field effects on chemi-ionization in droplet burning
… of the electric field is modelled using the Ionic Wind and Ohmic Heating. Furthermore, two distinguished limits of weak and strong field are studied to understand the charge redistribution in both cases. Based on the numerical results, an increase in the mass burning rate is observed with …

Performance characterization of electrohydrodynamic propulsion devices
… with neutral molecules in a phenomenon termed an ionic wind. Electrohydrodynamic thrusters generate thrust by using two or more electrodes to ionize the ambient fluid and create an electric field. In this thesis, electrohydrodynamic thrusters of single- and dual-stage configurations were tested. …
