On the reliability of a modification of the fluid model of a glow discharge incorporating the calculation of the local EEDF at each point in space Wang, Ying; Rafatov, İsmail; Bogdanov, Eugeny; Kudryavtsev, Anatoly; Yao, Jingfeng; Yuan, Chengxun (2025-02-01) An analysis of the approach named “Space-Dependent Electron Energy Distribution Function (EEDF) Modeling” in the COMSOL Multiphysics's Plasma Module is carried out. This modeling approach allows a wide range of users to de...
Computational study of characteristics of atmospheric pressure glow discharge in helium Islamov, Gubad; Eylenceoglu, Ender; Rafatov, İsmail (2025-02-01) Numerical analysis of an atmospheric pressure glow discharge (APGD) in helium is carried out. Numerical models are spatially one- and two-dimensional and based on drift-diffusion theory of gas discharges. On the basis of t...
On fundamental inconsistencies in a commonly used modification of a fluid model for glow discharge Zhou, Chen; Rafatov, İsmail; Wang, Ying; Kudryavtsev, Anatoly; Yuan, Chengxun; Yao, Jingfeng; Zhou, Zhongxiang (2024-07-01) This work considers the fundamental contradictions in the concept of one of the most well-known and widely used modifications of the fluid model for simulation of a glow discharge (GD), the ‘local mean energy approximation...
Effect of the cathode surface temperature on the cathode fall layer parameters: experiment and simulation Simonchik, Leanid; Tomkavich, Mikalai; Islamov, Gubad; Eylenceoglu, Ender; Rafatov, İsmail (2024-02-01) Combined experimental and numerical studies reveal a significant effect of the cathode temperature on the basic parameters (such as the electric field profile, thickness of the cathode fall layer, current density, and gas ...
On the conditions of applicability of commonly used modification of a fluid model for glow discharge Kudryavtsev, A.; Rafatov, İsmail; Yuan, C. (2024-01-01) The reliability of a numerical model is determined by its the least accurately known component. Such a component in fluid models of glow discharges is the description of electrons, which are far from equilibrium. This is e...
