A Comparative Numerical Analysis of Electric Field Distribution in Simple and Multi-Tube DBD Ozone Generators

This paper introduces a comparative investigation between two ozone generators. The first generator features a design comprising a cylindrical stainless steel electrode grounded, an inner aluminum electrode connected to high voltage, and a glass tube serving as a dielectric barrier discharge. Conversely, the second generator, termed a multi-tube ozone generator, was also study. In this design, a stainless steel electrode is grounded as the first electrode, and a high-voltage aluminum electrode with a glass tube functions as the dielectric barrier discharge. It is noteworthy that both generators share an equal discharge volume, estimated at 4.27 cm³. The investigation utilized the simulation program Comsol Multiphysics 5.6. Analysis of the simulation results for the electric field strength in the two generators indicates that the multi-tube ozone generator exhibits a superior electric field distribution compared to the first ozone generator, implying increased efficiency in ozone generation.
