“…It can also be explained with respect to the electrical capacitance. Higher electrical capacitance can be achieved by higher electric permittivity and stronger plasma can be generated by a dielectric with higher electrical capacitance due to the reactor impedance [18,38]. The result from this section of the experiment shows that quartz as the dielectric material has better performance than pyrex in terms of both power consumption and NOx removal efficiency.…”

“…Selecting a material with a higher electric permittivity coefficient results in a higher discharge power and therefore the gas breakdown will happen at lower applied voltage and more NOx can be removed during the plasma treatment. The electric field at radius r in the discharge gap is defined as [18]: l is equal to the dielectric thickness (…”

“…They showed that by using the Multineedle-to-Cylinder system, higher performance of DBD reactor can be achieved compared to the regular DBD reactor. In 2012, Wang et al [18] investigated different parameters of the DBD reactor, such as electrode shape and material. They showed that by using tungsten as the material of inner electrode, a higher NO removal efficiency was achieved compared to copper and stainless steel electrodes due to the higher secondary electron emission coefficient.…”

In this paper, a comprehensive study of a DBD reactor is conducted to investigate the optimum operating conditions of the reactor for NOx treatment. For each parameter, the objective is to find the maximum NOx removal efficiency with the minimum consumed power. Different effective parameters of the reactor i.e. electrode length and diameter, electrode and dielectric materials as well as parameters of power generator, i.e. voltage and frequency, are investigated. The results show that for this configuration, the electrode with 20 cm length and 10 mm diameter has the best performance. Aluminum as the inside electrode material and quartz as the dielectric material are selected. Furthermore, the optimum value for the pulse frequency is 16.6 kHz. For the mentioned optimum conditions, the NOx removal efficiency achieved is equal to almost 82% at the input power of 486 W. Furthermore, the highest achieved NOx removal is almost 92% at the input power of 864 W. The results of this paper can be used to reduce the energy consumption of NTP systems to acceptable levels.

“…This trend is also in accordance with the previously reported literature in a co-axial electrode configuration. 2,17 A higher current corresponds to a stronger discharge, which would translate in better decomposition efficiency of pollutants. The trends obtained for discharge current as a function of applied voltage magnitude and frequency are consistent with the experimental results of Du et al, 40 who studied the NOx removal from diesel exhaust using co-axial DBD and observed that the removal rate of NOx first increased and then decreased with increasing the magnitude and frequency of the voltage.…”

“…Although the typical target molecules in gas cleaning applications in co-axial DBD reactors are NO x , SO x , CH 4 , CO 2 , Toluene, Naphthalene, etc., their detailed plasma chemistries frequently involve tens of species and hundreds or even thousands of reactions including the electron impact, electronion recombination, neutral-neutral, ion-neutral, and ion-ion reactions. 7 In addition to the complexity, the large number of reactions also leads to greater uncertainty in the model predictions as the rate constants used are mostly approximate.…”

In this work, a one-dimensional numerical fluid model is developed for co-axial dielectric barrier discharge in pure helium and a parametric study is performed to systematically study the influence of relative permittivity of the dielectric barrier and the applied voltage amplitude and frequency on the discharge performance. Discharge current, gap voltage, and spatially averaged electron density profiles are presented as a function of relative permittivity and voltage parameters. For the geometry under consideration, both the applied voltage parameters are shown to increase the maximum amplitude of the discharge current peak up to a certain threshold value, above which it stabilized or decreased slowly. The spatially averaged electron density profiles follow a similar trend to the discharge current. Relative permittivity of the dielectric barrier is predicted to have a positive influence on the discharge current. At lower frequency, it is also shown to lead to a transition from Townsend to glow discharge mode. Spatially and time averaged power density is also calculated and is shown to increase with increasing relative permittivity, applied voltage amplitude, and frequency.

In this research, the polypropylene (PP) sheets used for automotive bumper surface were treated using two methods: air atmospheric gliding arc plasma and flame modifications. Atomic force microscopy was applied to study the morphology of surfaces before and after treatment processes. While calculating the surface free energy (SFE), contact angle of the surfaces was measured, and the chemical composition of the PP surface was analyzed using X‐ray photoelectron spectroscopy. Surface modifications by gliding arc plasma increased the ratio of the oxygen and nitrogen atoms on the surface by 100%, indicating that polar chemical functionalities form on the surface. The surface morphology was highly affected by gliding arc plasma treatments, which triggered an impact on roughness and etching. It was also found that the SFE was drastically increased by certain modifications. Noticeable improvement was also observed in wettability by the gliding arc plasma technique. In the next stage, polyurethane paints were coated on the treated and untreated PP surfaces. Then, we examined the flame and gliding arc plasma treatments' effect on coating properties of PP bumper, adhesion analysis, water immersion resistance, and sulfuric acid resistance. Finally, high‐pressure carwash test and gloss analysis were conducted on the treated and untreated coated sheets, respectively.
