Abstract
Misty plasmas are typically defined as plasma containing small liquid droplets and therefore makes it a multiphase system. In an attempt to characterize an atmospheric pressure misty plasma discharge, a flat plate dielectric barrier discharge (DBD) is designed that utilizes a stagnation flow field for the introduction of water droplet laden flow. The water droplets in the form of spray are introduced through an annulus from the bottom plate, which also acts as the grounded electrode. The interaction of the liquid spray and the DBD plasma discharge is characterized, and compared with glow discharge, through measurements of the voltagecurrent characteristics, optical emission spectrum and discharge visualization.
