This work is devoted to the numerical study of characteristics of dielectric barrier discharge maintained in a coaxial reactor in atmospheric pressure CO2. The numerical model is based on the drift-diffusion theory of gas discharges, and takes into account the gas heating in a self-consistent manner. The effect of incorporating gas heating into the discharge properties, specifically, on CO2 decomposition, is investigated for wide range of amplitude and frequency of the applied voltage. Calculations revealed a significant effect of gas heating on CO2 conversion. Calculations with a constant (room) gas temperature led to a strong overestimation of CO2 conversion level.

Micro processing by intense fast electron beam Goktas, H; Kirkici, H; Oke, G; Udrea, M (2001-06-22) Generation of intense electron beams by superposing two discharges, namely a low pressure do glow discharge and a high current pulsed discharge at pressures and voltages very similar to that of the pseudo-spark gap devices, has been reported previously [1, 2]. The small diameter, high peak current and short pulse length are the characteristics of the electron beam generated using this technique. In this technique, no high vacuum facilities are necessary, and many applications such as micro processing, X-ray...
One-dimensional fluid and hybrid numerical analysis of the plasma properties in the discharge channel of a Hall thruster YUNCULER, Cinar; Rafatov, İsmail; Ulusen, DEMET (2018-01-01) One-dimensional fluid and hybrid fluid-kinetic numerical codes are developed and applied to the analysis of axial distributions of plasma properties in the discharge channel of a Hall-effect thruster. Within the hybrid model ions are described by the kinetic Vlasov equation, while electrons and neutral atoms are treated as fluids. The results obtained from fluid and hybrid models are compared. Different operating regimes such as damped, periodic, and aperiodic irregular oscillations about the stationary sta...
Parametric study of coaxial dielectric barrier discharge in atmospheric pressure argon Li, Hui; Yuan, Chengxun; Kudryavtsev, Anatoly; Katircioglu, T. Yasar; Rafatov, İsmail (2021-11-01) A parametric study of the characteristics of coaxial dielectric barrier discharge sustained in atmospheric pressure argon is carried out. The numerical model is based on the drift-diffusion theory of gas discharges. The integral characteristics of the discharge, such as the root mean square of the discharge current, the period average dissipated power, and the efficiency of the power deposition, are explored in the parameter space spanned by the voltage amplitude and frequency of the applied AC field, the b...
A mass spectrometric study on plasma reactions of styrene and methyl methacrylate Özden (Orhan), Bilge; Hacaloğlu, Jale; Akovali, Güneri (1991-01-01) High frequency gas discharge plasma reactions of styrene and methyl methacrylate at low pressure have been studied mass spectrometrically. When styrene was used as a monomer, the most important reaction was plasma state polymerization; some decomposition of styrene and the formation of a small amount of C2H4 were detected. Under the same conditions, methyl methacrylate was decomposed mainly to CO, CO2 and C2H4.
Simulations on glow discharge: development and validation of one-dimensional kinetic model by particle in cell/monte carlo collision method Tiryaki, Özgecan; Çakır, Serhat; Department of Physics (2019) Numerical codes for glow discharge plasma simulations were developed by using Particle in Cell/Monte Carlo Collision (PIC/MCC) method. The model is one-dimensional in coordinate space and three-dimensional in velocity space (1d3v). A modification of Direct Simulation Monte Carlo (DSMC) method known as null-collision method was used for particle collisions. MPI and sub-cycling were used for speed up. The code was validated using benchmarks for capacitively coupled helium discharges and tested with three-dime...
