Jet Flow Focusing by Corona Discharge for Fluidic Application

Abstract

This paper presents a study on a jet flow assisted by low net charge ion wind generated from bipolar corona setup, adding momentum to the bulk flow directed alongside the electrodes and focused in the middle of interelectrode space. It was confirmed that with only 27.1 mW of consumed discharge power, the corona helped to focus and increased the flow peak velocity up to 71.6%, i.e., from 1.41 m/s to 2.42 m/s. Because the generated air flow remains neutral, this work can contribute to the development of multi-axis fluidic inertial sensors, fluidic mixing and analysis with space constraints and/or where neutralized discharge process is required.
