Ozone generation using screw-type electrodes with different distance peak to peak was studied, with the view to comparing the effectiveness of the two technologies in improving for high ozone concentration. Current density, heat flux, and distribution electric potential were performed by using simulation software Ansys. These simulations indicate that the screw-type electrode with a distance of 2 mm generates the higher current density, the result is the same as the initial assumption that the screw distance 2 mm will be better than distance 1.5 mm because it has lower heat flux. Experimental work confirms that a screw model with a distance of 2 mm also has high ozone concentration than a distance 1.5 mm screw model due to current density making electric field strength also higher to produce high ozone concentration, as was also noted by previous authors.

“…In the case of DBD, several investigations have explored the impact factors of different DBD morphologies under various driving power sources, DBD structures, and working gases [13][14][15][16][17][18]. Current studies demonstrate the close relationship between the morphological development and evolution of the discharge and microscopic factors such as the electric field distribution, particle species, and spatial distribution of the plasma [19][20][21][22][23]. However, the development and evolution of the morphology of PDBD and the related impact factors have been less explored.…”

The discharge morphology of pulsed dielectric barrier discharge (PDBD) plays important roles in its applications. Here, we systematically investigated the effects of voltage amplitude, discharge gap, and O2 content on the PDBD morphology, and revealed the possible underlying mechanism of the U-shape formation. First, the morphological evolution under different conditions were recorded. A unique U-shape region appears in the middle edge region when the gap is larger than 2 mm, while the entire discharge region remains columnar under a 2 mm gap in He PDBD. The width of the discharge and the U-shape region increase with the increase of voltage and decreases with the increase of the gap and O2 content. To explain this phenomenon, then a two-dimensional symmetric model was developed to simulate the spatiotemporal evolution of different species and calculate the electric thrust. The discharge morphology evolution directly corresponds to the excited state atomic reduction process. The electric thrust on the charged particles mainly determines the reaction region and strongly influences the U-shape formation. When the gap is less than 2 mm, the electric thrust is homogeneous throughout the entire region, resulting in a columnar shape. However, when the gap is larger than 2 mm or O2 is added, the electric thrust in the edge region becomes greater than that in the middle, leading to the U-shape formation. Furthermore, in He PDBD, the charged particles generating electric thrust are mainly electrons and helium ions, while in He/O2 PDBD those generate electric thrust at the outer edge of the electrode surface are mainly various oxygen-containing ions.
