The liquid-jet phenomena induced by the electrohydrodynamical (EHD) pumping, were investigated in isothermal dielectric liquids without a direct charge injection at a metal/liquid interface. A pseudo-doughnut to plane electrode system was used to generate an EHD liquid-jet, and the properties of liquid-jet were measured using four different dielectric liquids (which are referred to as DBDN, BCRA, Tr-Oil and FS-Oil in this paper). The maximum velocity and pumping pressure achieved were 1.5m/s and 5.5kPa, respectively, at 23kV with about 2.5W of electrical consumption in BCRA.
