Electric wind generation by nanosecond repetitively pulsed microplasmas
Résumé
A nanosecond repetitively pulsed microplasma generated between two tungsten electrodes in a pin-to-pin configuration is used as a supply of charged species to produce an electrohydrodynamic phenomenon when placed near a DCbiased electrode. We employed high-frequency particle image velocimetry in order to study the produced flow. The generated flow velocities are around 2 m s −1 with a deposited average power on the order of 1 W. The main characteristics of this flow and the impact of the frequency and the DC field are discussed. In the end, we further explain the impact of each microplasma event on flow modification.
