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...
Numerical simulation of transient turbulent flow in a heated pipe
Uygur, Ahmet Bilge; Selçuk, Nevin; Oymak, Olcay; Department of Chemical Engineering (2002)
A computational fluid dynamics (CFD) code based on direct numerical simulation (DNS) and the method of lines MOL approach developed previously for the solution of transient two-dimensional Navier-Stokes equations for turbulent, incompressible, internal, non-isothermal flows with constant wall temperature was applied to prediction of turbulent flow and temperature fields in flows dominated by forced convection in circular tubes with strong heating. Predictive ability of the code was tested by comparing its r...
Numerical simulation of scour and backfilling processes around a circular pile in waves
Baykal, Cüneyt; Fuhrman, D. R.; Jacobsen, N. G.; Fredsoe, J. (2017-04-01)
This study continues the investigation of flow and scour around a vertical pile, reported by Roulund et al. (2005). Flow and scour/backfilling around a vertical pile exposed to waves are investigated by using a three-dimensional numerical model based on incompressible Reynolds averaged Navier-Stokes equations. The model incorporates (1) k-omega turbulence closure, (2) vortex shedding processes, (3) sediment transport (both bed and suspended load), as well as (4) bed morphology. The numerical simulations are...
Numerical Simulation of Flow through Stenotic Artery
Tarman, Işık Hakan (2009-01-01)
Numerical simulation of flow through stenotic artery is performed using spectral element method in an axisymmetric geometry. This method, under suitable conditions, provides high accuracy The use of the weak form of the governing model equations, brings flexibility in treating solution domains with nonstandard geometry. The solenoidal character of the flow is preserved by the treatment of the pressure in a natural way in the numerical formulation. The use of Legendre-Lobatto grid points with its denser dist...
