Abstract: One of an electrohydrodynamics (EHD) phenomenon is the
induced flow of a functional fluid in the presence of an electric field. In
this paper, we describe a small pump in which the flow is generated by such
an EHD phenomenon. In the case of pumps based on cylindrical electrodes,
which thus far have been the focus of our research on EHD pumps, the total
circumference length of the edge of the holes in the electrode that
generates the rotational flow is small, leading to a small overall
one-directional flow velocity. To increase this area, we produced two
different electrode pumps in which the electrode (cylindrical; 6 mm
diameter, 1 mm width) contains multiple holes. We measured the pressure-flow
rate characteristics of our pumps and compared their performances.
