Numerical modeling of re-suspension and transport of fine sediments in coastal waters
Karadoğan, Erol; Özhan, Erdal; Department of Civil Engineering (2004)
In this thesis, the theory of three dimensional numerical modeling of transport and re-suspension of fine sediments is studied and a computer program is develped for simulation of the three dimensional suspended sediment transport. The computer program solves the three dimensional advection-diffusion equation simultaneously with a computer program prepared earlier for the simulation of three dimensional current systems. This computer program computes the velocity vectors, eddy viscosities and water surface ...
Experimental investigation of single phase liquid flow and heat transfer in multiport minichannels
Altınöz, Mesru; Güvenç Yazıcıoğlu, Almıla; Baker, Derek Keıth; Department of Mechanical Engineering (2013)
This thesis aims to experimentally investigate pressure drop and heat transfer characteristics of single phase water flow in rectangular minichannels. The small channels are an area of interest in heat transfer field since 1970’s owing to their enhanced heat transfer characteristics. However, the heat transfer and pressure drop characteristics of these channels are not fully established as there is a wide number of studies in literature showing inconsistent results with each other. In order to investigate t...
Radial basis function and dual reciprocity boundary element solutions of fluid dynamics problems
Gürbüz, Merve; Tezer Sezgin, Münevver; Department of Mathematics (2017)
In this thesis, the two-dimensional, laminar steady or unsteady flow of a viscous, incompressible, electrically conducting fluid is considered in channels of several geometries under the impact of a uniform magnetic field with different orientations. Magnetohydrodynamic (MHD) flow governed by the hydrodynamic and electromagnetic equations is solved numerically with or without Stokes approximation and with or without magnetic induction due to the large or small values of Reynolds and magnetic Reynolds number...
Numerical investigation of the viscoelastic fluids
Yapıcı, Kerim; Uludağ, Yusuf; Department of Chemical Engineering (2008)
Most materials used in many industries such as plastic, food, pharmaceuticals, electronics, dye, etc. exhibit viscoelastic properties under their processing or flow conditions. Due to the elasticity of such materials, deformation-stress in addition to their hydrodynamic behavior differ from simple Newtonian fluids in many important respects. Rod climbing, siphoning, secondary flows are all common examples to how a viscoelastic fluid can exhibit quite distinctive flow behavior than a Newtonian fluid would do...
Seismic response of a rubble mound breakwater in Turkey
Yuksel, Y; Çetin, Kemal Önder; Ozguven, O; Isik, NS; Cevik, E; Sumer, BM (Thomas Telford Ltd., 2004-12-01)
This paper presents analyses of seismically induced deformations at Eregli Fishery Port breakwater during the 1999 Kocaeli (Izmit), Turkey earthquake. The paper discusses: (a) observed ground deformations and displacements after the earthquake; (b) the results of field investigations by means of borings including standard penetration tests; (c) analyses of observed deformation mechanisms by a suite of methods; and (d) the possible contribution of soil liquefaction rupture on the observed deformations.
