Combined effects of electrode geometry and airflow streamlines patterns on ozone production of a cylindrical dielectric barrier discharge

We studied ozone generation of a surface dielectric discharge in an annular space of the cylindrical discharge chamber with tangential air input and four axial outputs. To enhance this generation, we focused on the combined effect of electric field distribution and streamline’s orientation concernin...

description We studied ozone generation of a surface dielectric discharge in an annular space of the cylindrical discharge chamber with tangential air input and four axial outputs. To enhance this generation, we focused on the combined effect of electric field distribution and streamline’s orientation concerning the active electrode by adjusting its geometry to a particular airflow. The aluminium active electrode consisted of rings, inclined rings, and axial strips. We used two types of this electrode, differing in the number of rings. We showed that for certain active electrode geometry and airflow, the concentration of generated ozone, production rate, and the ozone production yield exhibit a local maximum. This effect can be used to select the most efficient working regime for commercial ozone generators.
