A numerical investigation of particle motions in a horizontal channel and interactions of these particles with Bénard cells resulting from the heating of the channel from the bottom is presented. A 3-D spectral-methods-based code is developed to solve the rotational form of incompressible Navier-Stokes equations with the energy equation and the small particle equation of motion in a two-way coupled manner. A new surface-force-based approach to coupling is introduced and the importance of two-way coupling is demonstrated. It has been observed that the interactions between particles and Bénard cells can lead to the transition of the cells from one periodicity length to another.

A numerical study of solidification and viscous dissipation effects on polymer melt flow in plane channels
Tutar, Mustafa; Karakuş, Ali (Walter de Gruyter GmbH, 2013-04-01)
The combined effects of solidification and viscous dissipation on the hydrodynamic and thermal behavior of polymer melt flow during the injection process in a straight plane channel of constant cross section are numerically studied by considering the shear-rate and temperature-dependent viscosity and transient-phase change behavior. A numerical finite volume method, in conjunction with a modified form of the Cross constitutive equation to account for shear rate, temperature-dependent viscosity changes and a...
A Numerical approach for the solutions of fluid dynamics problems in the presence of magnetic field
Oğlakkaya, Fatma Sidre; Bozkaya, Canan; Department of Mathematics (2018)
This thesis is conducted to investigate numerically the two-dimensional steady or unsteady, laminar flow of viscous, incompressible and electrically conducting fluids in complex geometries subject to either uniform inclined magnetic field or nodal magnetic sources. Specifically, the hydromagnetic natural/mixed convection of either conventional fluid or water-based nanofluid flow and the heat transfer are considered in irregular enclosures with wavy walls. The equations governing the steady magnetohydrodynam...
The Investigation of Electronic, Elastic and Vibrational Properties of an Interlanthanide Perovskite: PrYbO3
KADEROĞLU, ÇAĞIL; SÜRÜCÜ, GÖKHAN; ERKİŞİ, AYTAÇ (2017-10-01)
The structural, mechanical, electronic and lattice dynamical properties of the PrYbO3 compound from the ABO(3)-type perovskite family have been investigated by performing the first-principles density functional theory calculations using the generalized-gradient approximation (GGA) with corrected Coulomb interactions (GGA+U). Structural parameters, formation energies and phase transition pressures for the five possible phases of this compound have been calculated. Then, the spin-dependent electronic band str...
A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons
Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01)
The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
A comparative ab initio study of the ferroelectric behaviour in KNO3 and CaCO3
Aydınol, Mehmet Kadri; Alpay, S. P. (IOP Publishing, 2007-12-12)
Potassium nitrate exhibits a reentrant phase transformation, where a metastable ferroelectric phase (gamma-KNO3) is formed upon cooling from high temperature. The layered structure of this ferroelectric phase is composed of alternating layers of potassium ions and nitrate groups; wherein, a central nitrogen atom is coordinated by three equilateral triangular oxygen atoms. The group layer is located less than midway between the cation layers, giving rise to a polar structure. From a structural perspective, t...
