Utilization of friction stir processing to improve the mechanical properties of gas metal arc welded 5083 aluminum alloy plates
Takht Firouzeh, Shahin; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2016)
Fatigue failure of the welded structures is a major problem in engineering applications. It is known that the heat affected zone (HAZ) of the welded Al-alloys is prone to fail due to coarse microstructure and poor mechanical properties. Therefore, any improvement in HAZ may extend the service life of the welded component. The hypothesis of this study is that localized application of friction stir processing (FSP) before welding may improve the mechanical properties of HAZ, and thus, may reduce the fatigue c...
Utilization of CFD tools in the design process of a Francis turbine
Okyay, Gizem; Aydın, İsmail; Department of Civil Engineering (2010)
Francis type turbines are commonly used in hydropower generation. Main components of the turbine are spiral case, stay vanes, guide vanes, turbine runner and the draft tube. The dimensions of these parts are dependent mainly on the design discharge, head and the speed of the rotor of the generators. In this study, a methodology is developed for parametric optimization by incorporating Matlab codes developed and commercial Computational Fluid Dynamics (CFD) codes into the design process. The design process s...
Utilization of fly ash-portland cement binary systems to control alkali-silica reaction
Çelen, Ahmet Ziya; Akgül, Çağla Meral.; Department of Civil Engineering (2019)
The highly alkaline pore solution of the portland cement concrete is not an ideal environment for certain reactive aggregates with poorly-crystalline or amorphous silica phases. In this environment, these aggregates partially or completely disintegrate resulting in formation of a hydrophilic, amorphous gel mainly composed of alkalis and water from the pore solution of the hydrated cement matrix and silica from the aggregates. The newly formed alkali-silica reaction (ASR) gel can expand by absorbing huge amo...
Utilization of GGBFS blended cement pastes in well cementing
Alp, Barış; Yaman, İsmail Özgür; Akın, Serhat; Department of Cement Engineering (2012)
In well cementing, the cement slurry is exposed to the conditions far different than those of ordinary Portland cement (PC) used in construction. After placement, hardened cement paste should preserve integrity and provide zonal isolation through the life of the well. American Petroleum Institute (API) Class G cement is the most common cement type used in various well conditions. Class G cement has a high degree of sulfate resistance which makes it more stable than PC when subjected to the compulsive well c...
Utilization of fiber loop ring down technique for sensing applications
Yolalmaz, Alim; Danışman, Mehmet Fatih; Bek, Alpan; Department of Micro and Nanotechnology (2017)
Fiber loop ring down (FLRD) spectroscopy is based on multiple interaction of laser light with sample/analyte. It is evolved from cavity ring down spectrometer with addition of optical fiber. Measurement accuracy rises with multiple interactions and this enhances the minimum detection limit compared to other spectrometers using single pass interaction such as FTIR, UV-VIS spectrometer. The other advantages of this technique are its insensitivity to laser fluctuation and detector performance. In this study, t...
