Abstract: Non-intrusive two-phase fluid pumping based on an
electrohydrodynamically (EHD) induced flow phenomenon with free liquid surface
exposed to gas-phase corona discharges is experimentally investigated.
Dielectric liquid flow generated near a corona discharge electrode progresses
toward an inclined plate electrode, and then climbs up the surface against the
gravitational force for an air-wave (AW) type EHD pump. The AW type EHD pump is
operated on ionic wind field along the inclined plate electrode. The pumping
performance of time-averaged liquid flow rate and the liquid-phase flow motion
are characterized. The liquid flow characteristics related to a dimensionless
parameter of corona discharge fields are presented.
