Pulsed Dielectric Barrier Discharge of Argon Gas in Gas–Liquid Two-Phase Flow

Pulsed dielectric barrier discharges are generated within bubbles of a gas-liquid two-phase flow that consists of argon bubbles and water. Discharge images were captured by using a high-speed video camera to understand the motion of discharge within bubbles, and an intensified charge-coupled device camera captured temporal discharge images at a nanosecond timescale.
