We studied asystem consisted of a planar glow discharge layer with short length in the forward direction and wide lateral dimensions, which iscoupled to a semiconductor layer with low conductivity. The whole structure is sandwiched between two planar electrodes, to which a dc voltage is applied. Experiments show that such a system can create different homogeneous stationary and homogeneous oscillating modes, patterns with spatial and spatiotemporal structures. We developed and applied full three-dimensional fluid numerical code to study temporal and spatial pattern formation in this system.

Numerical modelling of spatio-temporal patterns in a DC-driven gas discharge-semiconductor system Özden, Gözde; Rafatov, İsmail; Karasözen, Bülent; Department of Scientific Computing (2015) In this thesis, numerical modelling of temporal and spatial pattern formation in the planar layered system, consisted of a DC driven planar gas discharge layer, coupled to high ohmic semiconductor layer, is carried out in 1D and 2D Cartesian geometry. Numerical model includes continuity equations for ions and electrons, the Poisson equation for the electric field, the energy balance equation for the background gas. The conditions correspond to a transition from the Townsend regime to the glow discharge. Cal...
Investigation of nonlinear oscillations in the gas discharge-semiconductor system: effect of different fluid modelling approaches Yeşil, Cihan; Rafatov, İsmail; Department of Physics (2018) The work deals with the study of nonlinear oscillations in a system, consisted of planar glow discharge layer, coupled to a high-ohmic semiconductor layer. The whole system is sandwiched between two planar electrodes, to which the DC voltage is applied. The discharge models are developed in Comsol Multiphysics (v5.2), and based on ﬂuid description of plasma, with drift-diﬀusion approximation for charged particle ﬂuxes. Numerical tests are carried out for the discharge in Nitrogen, with GaAs semiconductor la...
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 in this system in the form of self-organized current filaments, which develop from the homogeneous stationary state by the Turing bifurcation. The numerical model reveals, for the first time, evidence of spontaneous division of the current filaments in this system, similar to that observe...
Numerical and Experimental Investigation of Newtonian Flow around a Confined Square Cylinder Tezel, Guler Bengusu; YAPICI, Kerim; Uludağ, Yusuf (Periodica Polytechnica Budapest University of Technology and Economics, 2019-01-01) The confined flow of a Newtonian fluid around a square cylinder mounted in a rectangular channel was investigated both numerically and experimentally. Ratio between the pipe and channel height, the blockage ratio, is kept constant at 1/4. The flow variables including streamlines, vorticity and drag coefficients were calculated at 0 <= Re <= 50 using finite volume method. The velocity terms in the momentum equations are approximated by a higher-order and bounded scheme of Convergent and Universally Bounded I...
Numerical analysis of formation of hexagonal and band structures in the gas discharge - semiconductor system Rafatov, İsmail (2015-09-01) The spontaneous formation of regular hexagonal and band structures in the current distribution of the gas discharge – semiconductor system is studied. The system consists of a planar glow discharge layer with short length in the forward direction and wide lateral dimensions, which is coupled to a planar semiconductor layer with low conductivity. The whole structure is sandwiched between two plane electrodes to which a dc voltage is applied. The choice of input parameters is guided by the experimental study ...
