|Abstract: ||Surface Dielectric Barrier Discharges (S-DBDs) have received renewed attention in recent years for their
potential application in emerging biomedical, environmental and agricultural applications. In most of these
applications, the plasma is not in direct contact with the substrate being treated and the transport of reactive species
from the plasma to the substrate is typically assumed to be controlled by diffusion. Here, we demonstrate that
generally this is not the case and that electrohydrodynamic (EHD) forces can produce jets that enhance the delivery
of these species, thereby influencing the efficacy of the S-DBD device. In particular, we have studied the
degradation of potassium indigotrisulfonate solutions exposed to S-DBDs generated in devices with annular
electrodes of diameters varying between 10mm and 50mm. All the devices were driven at constant linear power
density (Watts per cm of plasma length) and although local plasma properties remained the same in all the devices, a
three-fold efficacy enhancement was observed for devices of diameter ~30mm due to EHD effects.|
