Three-dimensional modelling of stratified coastal waters
Balas, L; Ozhan, E (2002-01-01)
An implicit baroclinic 3-D model developed to simulate the circulation in coastal waters, is presented. The model has hydrodynamic, transport and turbulence model components. It is a composite finite difference-finite element model. In the horizontal plane, second order central finite differences on a staggered scheme and in the vertical Galerkin method with linear shape functions are used. Implicit equations are solved by Crank Nicholson method which has second order accuracy in time also. Developed model ...
Three-dimensional modeling of intersonic shear-crack growth in asymmetrically loaded unidirectional composite plates
Yu, C.; Pandolfi, A.; Ortiz, M.; Çöker, Demirkan; Rosakis, A.J. (Elsevier BV, 2002-12)
An anisotropic cohesive model of fracture is applied to the numerical simulation of Coker and Rosakis experiments (2001). In these experiments, a unidirectional graphite-epoxy composites plate was impacted with a projectile, resulting in an intersonic shear-dominated crack growth. The simulations account for explicit crack nucleation-through a self-adaptive remeshing procedure-crack closure and frictional sliding. The parameters used in the cohesive model are obtained from quasi-static fracture experiments,...
Three-dimensional numerical modelling of temporal and spatial pattern formation in a dc-driven gas discharge-semiconductor system
Rafatov, İsmail (IOP Publishing, 2016-12-01)
A three-dimensional numerical model is developed and applied to study the temporal and spatial pattern formation in the planar layered system, consisting of a glow discharge layer, coupled to a high ohmic semiconductor layer. The whole system is sandwiched between two planar electrodes, to which a dc voltage is applied.
Three-dimensional modeling of a high temperature polymer electrolyte membrane fuel cell at different operation temperatures
Caglayan, Dilara Gulcin; Sezgin, Berna; DEVRİM, YILSER; Eroğlu, İnci (2016-06-22)
A three-dimensional model for a high temperature polymer electrolyte membrane (PEM) fuel cell having an active area of 25 cm(2) is developed. Triple mixed serpentine flow channel single cell with phosphoric acid doped polybenzimidazole (FBI) membrane is used in the model. Steady-state, isothermal, single phase assumptions are defined for the system. The model is simulated at different temperatures ranging from 100 to 180 degrees C to investigate the influence of operation temperature on the performance of t...
Three-Dimensional Reconstruction of Human Corneas by Tissue Engineering (CORNEA ENGINEERING)
Hasırcı, Vasıf Nejat(2007-12-31)
The goal of the proposed research project is to reconstruct a human cornea in vitro, for use both in corneal grafting and as an alternative to animal models for cosmeto-pharmacotoxicity testing. The project responds to the urgent need to develop new forms of corneal replacements as alternatives to the use of donor corneas, in view of the worldwide shortage of donors, the increasing risk of transmissible diseases, the widespread use of corrective surgery, which renders corneas unsuitable for grafting, and th...
