Fluid model of dc glow discharge with nonlocal ionization source term
Rafatov, İsmail; KUDRYAVTSEV, A. A. (2012-06-29)
We developed and tested a simple hybrid model for a glow discharge, which incorporates nonlocal ionization by fast electrons into the fluid framework. Calculations have been performed for an argon gas. Comparison with the experimental data as well as with the hybrid (particle) and fluid modelling results demonstated good applicability of the proposed model.

Dinescu, Cristian; Hirsch, Charles; Leonard, Benoît; Baran, Özgür Uğraş; Platschorre, Arie-Willem; Alessio, Rosario; Belluzzo, Damiano (2006-01-01)
The paper presents an integrated software tool for the hydroplaning simulation based on a weak coupled fluid-structure interaction model. The integrated modules are a flow solver FINE™/Hexa designed to solve the complex two-phase flow surrounding the tire numerically, based on unstructured hexahedral grids, the FEM solver MSC.Marc/MSC.Mentat which predicts the transients of the tire's structure, a coupling module for efficient and accurate transfer of the essential variables between the flow and FEM solvers...
Fluid-structure interaction analysis in external flows using Linearized Euler solver
Ardıç, Ata Tankut; Baran, Özgür Uğraş; Ciğeroğlu, Ender; Department of Mechanical Engineering (2022-8)
Flutter is an aeroelastic instability that requires numerous fluid-structure interaction (FSI) analyses during the design process of an aircraft. Even with technology of today, numerical solution of FSI problems is a challenge as these of problems require a high amount of computational power. Most of the computational cost stems from the computational fluid dynamics analysis (CFD) part of the computation, and time-dependent nature of the problem. Harmonic methods, which are very cost-efficient compared to u...

ALTINTAŞ, OLCAY; AKSOY, MURAT; AKGÖL, OĞUZHAN; ÜNAL, EMİN; KARAASLAN, MUHARREM; Sabah, Cumali (The Electrochemical Society, 2017-01-01)
We propose a design of a metamaterial based sensor to be used in various applications including micro-fluid, strain and rotation sensing. The structure has a simple geometry composed of a single circular split ring resonator (CSRR) and it is possible to adjust the resonance frequency in the region of desired band. The resonance frequency is carefully selected so that the materials to be sensed have linear dielectric curves at that particular frequency range which iscrucial to design accurate sensing charact...
Fluid-structure interactions with both structural and fluid nonlinearities
Bendiksen, O. O.; Seber, G. (Elsevier BV, 2008-08-19)
In this study, we consider a class of nonlinear aeroelastic stability problems, where geometric nonlinearities arising from large deflections and rotations in the structure interact with aerodynamic nonlinearities caused by moving shocks. Examples include transonic panel flutter and flutter of transonic wings of high aspect ratio, where the presence of both structural and aerodynamic nonlinearities can have a dramatic qualitative as well as quantitative effect on the flutter behavior. Both cases represent i...
