“…Thus ion flux along the electric field transfers its momentum to the weakly dipole neutral molecules. This results in the so-called ionic wind or an electrohydrodynamically induced gas flow [1][2][3][4][5][6][7][8][9][10]. When the electrode configuration forms an unsymmetrical electric field distribution, the unidirectional gas flow can be generated, i.e.…”

2D Particle Image Velocimetry (PIV) measurements were performed in a wirenonparallel plates type electrohydrodynamic (EHD) gas pump. The effect of electrode configuration and polarity of the active electrode on the flow pattern inside the pump was studied. One can deduce from the obtained flow patterns that the flow generated inside the EHD pump is three dimensional. The vortices formed inside the EHD gas pump have negative effect on pumping capabilities of the pump since the vortices may block and suppress the generated flow. The PIV results will be compared with a numerical modelling of the flow, based on k-E model.

“…Several electrode geometries have been studied for EHD gas pumps, such as needle-to-mesh, needle-toring, wire-to-rod, wire-nonparallel plates etc. [1][2][3][4][5][6][7][8][9][10], however, sharp edge electrode such as needle ore blade usually become unstable due to transition from corona to spark discharge [5].…”
