Bubbling Water‐Treating DBD Plasma Device Optimization Using Experimental and Computational Methods

Year: 2025

Type: article

Abstract: ABSTRACT A dry air atmospheric pressure volume dielectric barrier discharge is employed to fix nitrogen in water. Producing nitrate for use as nitrogen fertilizer is the primary motivation. A 0D chemistry model is developed and informed by the electrical, and geometric characteristics of the device and the plasma gas temperature. Modeled ozone and nitrate densities are compared to those measured experimentally in the plasma effluent and treated liquid for a range of gas temperatures. Modeled and measured ozone densities are in good agreement; however, the model lacks the liquid chemistry to properly represent the measured nitrate density. A gas temperature‐based shift from ozone to producing regimes is observed in both experiment and model, and the reactions responsible are evaluated.
