This study aims to estimate the critical fluid flow velocity for preventing the development of a stationary bed using empirical correlations valid for horizontal and highly inclined wellbores that can be easily used at the field. For this purpose, experiments have been conducted at METU-PETE Cuttings Transport Flow Loop for various conditions. Observations showed that a stationary bed is developed when the fuid velocity is less than 6.0 ft/s, and a critical fluid velocity of 8.0 ft/s is required to establish a no-bed condition. Results showed that the critical velocity and the thickness of the stationary bed, if developed, could be estimated with a reasonable accuracy.

Investigation of fracture behavior of steel/steel laminates Şimşir, Mehmet; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2004) A study is carried out into fracture behavior of steel/steel laminates both experimentally and through finite element analysis (FEM). The laminates produced by hot pressing consisted of low carbon and medium carbon steels with two volume fractions; 0.41 and 0.81. Fracture toughness, JIC has been measured using partial unloading technique assuming a critical value of crack extension. The technique is initially applied to monolithic material and then to the laminates in crack divider orientation. Evaluation o...
Theoretical and experimental investigation of bulk glass forming ability in bulk amorphous alloy systems Ayas, Can; Mekrabov, Amdulla O.; Department of Metallurgical and Materials Engineering (2005) In this study molecular dynamics simulation program in NVT ensemble using Velocity Verlet integration was written in order to investigate the glass forming ability of two metallic systems. The Zn-Mg system, one of the frontiers of simple metal-metal metallic glasses and Fe-B, inquiring attention due to presence of many bulk glass forming alloy systems evolved from this binary with different alloying element additions. In addition to this, atomistic calculations on the basis of ordering were carried out for ...
Numerical modeling of short term morphological changes around coastal structures and at the river mouths Demirci, Ebru; Baykal, Cüneyt; Güler, Işıkhan; Department of Civil Engineering (2016) In this study, XBeach, a two dimensional depth averaged numerical model developed mainly for simulating nearshore hydro- and morphodynamics is applied to two case studies; i) laboratory experiments on short-term morphological changes around a detached breakwater and a T-groin and ii) a fluvial dominated coastal flooding event at the Manavgat river mouth between dates, 4th and 15th December, 1998. In the first part of study, the numerical model is calibrated for the wave, current and bottom evolution conditi...
Nonlinear resonances of axially functionally graded beams rotating with varying speed including Coriolis effects Lotfan, Saeed; Anamagh, Mirmeysam Rafiei; Bediz, Bekir; Ciğeroğlu, Ender (2021-11-01) The purpose of the current study was to develop an accurate model to investigate the nonlinear resonances in an axially functionally graded beam rotating with time-dependent speed. To this end, two important features including stiffening and Coriolis effects are modeled based on nonlinear strain relations. Equations governing the axial, chordwise, and flapwise deformations about the determined steady-state equilibrium position are obtained, and the rotating speed variation is considered as a periodic distur...
Vibration Fatigue Analysis of a Cantilever Beam Using Different Fatigue Theories Eldoğan, Yusuf; Ciğeroğlu, Ender (2014-02-11) In this study, vibration fatigue analysis of a cantilever beam is performed using an in-house numerical code. Finite element model (FEM) of the cantilever beam verified by tests is used for the analysis. Several vibration fatigue theories are used to obtain fatigue life of the cantilever beam for white noise random input and the results obtained are compared with each other. Fatigue life calculations are repeated for different damping ratios and the effect of damping ratio is studied. Moreover, using strain...
