Analysis of parameters of coaxial dielectric barrier discharges in argon flow at atmospheric pressure
Li, Hui; Yuan, Chengxun; Kudryavtsev, Anatoly; Astafiev, Aleksandr; Bogdanov, Evgeny; Katircioglu, T. Yasar; Rafatov, İsmail (2021-04-01)
This work deals with the numerical and experimental investigation of atmospheric pressure dielectric barrier discharges (DBDs). In the experiment, the current and voltage of DBD sustained in an argon flow in coaxial discha...
Introduction to Simulation Methods for Gas Discharge Plasmas
Rafatov, İsmail; Kudryavtsev, Anatoly (Institute of Physics Publishing (IOP), 2020-12-01)
Gas discharge plasma is the most common type of low-temperature plasma, with a large number of practical applications covering almost all areas of modern science and technology. This book is an introduction to the numerica...
Transition from periodic to chaotic oscillations in a planar gas discharge-semiconductor system
Yuan, Chengxun; Yeşil, Cihan; Yao, Jingfeng; Zhou, Zhongxiang; Rafatov, İsmail (IOP Publishing, 2020-06-01)
The work studies the transition from periodic to chaotic oscillations in a dc-driven planar gas discharge with a high-ohmic electrode. The applied voltage and resistance of the semiconductor layer act as control parameters...

Numerical evidence of spontaneous division of dissipative solitons in a planar gas discharge-semiconductor system
Rafatov, İsmail (AIP Publishing, 2019-09-01)
This work deals with the formation of patterns of spatially localized solitary objects in a planar semiconductor gas-discharge system with a high Ohmic electrode. These objects, known as dissipative solitons, are generated...
Transition from homogeneous stationary to oscillating state in planar gas discharge-semiconductor system in nitrogen: Effect of fluid modelling approach
Rafatov, İsmail; Yeşil, Cihan (2018-08-01)
A laterally extended dc-driven system of planar gas discharge with a high-ohmic semiconductor electrode is considered. Numerical models are based on the fluid equations of plasma with drift-diffusion approximation for part...
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 mod...

PIC/MCC analysis of a photoresonance plasma sustained in a sodium vapor
SARIKAYA, C. Kusoglu; Rafatov, İsmail; KUDRYAVTSEV, A. A. (2017-08-01)
A parallel 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) code was derived and applied for the investigation of the formation of photoplasma in sodium vapor. The effects of particle weighting and the Courant number ...
An evidence of period doubling bifurcation in a dc driven semiconductor-gas discharge plasma
MANSUROGLU, D.; Uzun Kaymak, İlker Ümit; Rafatov, İsmail (2017-05-01)
We present an experimental study of nonlinearity observed in a dc driven semiconductor-gas discharge system. The plasma glow is generated using planar electrodes in a vacuum chamber filled with nitrogen gas at partial atmo...
