Modeling of flow in porous and fractured media is a very important problem in reservoir engineering. As for numerical simulations conventional Navier-Stokes codes are applied to flow in both porous and fractured media. But they have long computation times, poor convergence and problems of numerical instabilities. Therefore, it is desired to develop another computational method that is more efficient and use simple rules to represent the flow in fractured media rather than partial differential equations. In this thesis Lattice Boltzmann Automaton Model will be used to represent the single phase fluid flow in two dimensional synthetic fractures and the simulation results obtained from this model are used to train Artificial Neural Networks. It has been found that as the mean aperture-fractal dimension ratio increases permeability increases. Moreover as the anisotropy factor increases permeability decreases with a second order polynomial relationship.

Numerical Study of the Aerodynamic Effects of Septoplasty and Partial Lateral Turbinectomy OZLUGEDIK, Samet; NAKIBOGLU, Gunes; Sert, Cüneyt; Elhan, Alaittin; Tönük, Ergin; Akyar, Serdar; Tekdemir, Ibrahim (Wiley, 2008-02-01) Objectives: To investigate, first, the effects of septal deviation and concha bullosa on nasal airflow, and second, the aerodynamic changes induced by septoplasty and partial lateral turbinectomy, using computational fluid dynamics (CFD).
Simulation of equal channel angular pressing applied to produce structures with ultrafine-sized grains Karpuz, Pinar; Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2009-01-01) Severe plastic deformation methods are of great interest in industrial forming applications, as they give rise to significant refinement in microstructures and improvements in mechanical and physical properties. In the 'equal channel angular pressing (ECAP)', which is the most common method for production of ultrafine grained bulk samples, very high plastic strains are introduced into the bulk material without any change in cross section. In this study, the plastic deformation behaviour of the materials sub...
Ambient synthesis of nanomaterials by in situ heterogeneous metal/ligand reactions Chang, Boyce S.; Thomas, Brijith; Chen, Jiahao; Tevis, Ian D.; Karanja, Paul; Çınar, Simge; Venkatesh, Amrit; Rossini, Aaron J.; Thuo, Martin M. (Royal Society of Chemistry (RSC), 2019-08-07) Coordination polymers are ideal synthons in creating high aspect ratio nanostructures, however, conventional synthetic methods are often restricted to batch-wise and costly processes. Herein, we demonstrate a non-traditional, frugal approach to synthesize 1D coordination polymers by in situ etching of zerovalent metal particle precursors. This procedure is denoted as the heterogeneous metal/ligand reaction and was demonstrated on Group 13 metals as a proof of concept. Simple carboxylic acids supply the etch...
Particle-based characterization of Ottawa sand: Shape, size, mineralogy, and elastic moduli Erdoğan, Sinan Turhan; Stutzman, P. E.; Garboczi, E. J. (Elsevier BV, 2017-10-01) The success of computational materials science models for cement and concrete, at the micrometer-to-millimeter scale, is based on careful characterization of the two main starting materials - cement and aggregates. Concrete is a complex material, and models based on over-simplified chemical, geometrical, and topological assumptions have limits on the behavior they can realistically simulate. In this paper, a sample of Ottawa sand was carefully characterized, since this material is used in laboratories all a...
Site-specific uniform hazard spectrum in Eastern Turkey based on simulated ground motions including near-field directivity and detailed site effects Sisi, Aida Azari; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (Springer Science and Business Media LLC, 2017-04-01) In this study, stochastic earthquake catalog of the Erzincan region in Turkey is generated based on synthetic ground motions. Monte Carlo simulation method is used to identify the spatial and temporal distribution of events. Ground motion time histories are generated using stochastic simulation methodology. Annual exceedance rate of each ground motion amplitude is calculated through statistical distribution of the complete set of ground motions. The results are compared with classical probabilistic seismic ...
