Three different fuels UO2-only, UO2-Gd2O3(5%), and UO2-Gd2O3(10%) were produced by sol-gel technique. Their powder characteristics such as flowability, BET surface area, average pore diameter, and cumulative pore volume were determined. The pore size distributions of powders, green pellets, and sintered fuels were determined by using a mercury porosimeter. The theoretical densities of sintered fuels were found to be 98.01, 95.3, and 95.9%, respectively. Their ruggedness fractal dimensions were 1.111, 1.044, and 1.042, while the fractal dimensions associated with the size distribution of grains were 1.44, 1.58, and 1.60, respectively.

Material characterization with terahertz time-domain spectroscopy Köseoğlu, Devrim; Bilikmen, Kadri Sinan; Department of Physics (2010) Terahertz time-domain spectroscopy systems were developed and used for the anaylsis and characterization of various materials. By using ultra-fast Ti:Sapphire and Er-doped fiber lasers, terahertz time-domain spectrometers of different configurations were constructed and tested. To increase the accuracy and sensitivity of the measurements, the systems were optimized for spectroscopic analysis. MBE grown nominally undoped epitaxial GaAs samples were used for the spectroscopic measurements. These samples were ...
EXPERIMENTAL AND NUMERICAL INVESTIGATION OF RADIAL-RADIAL SWIRLERS UNDER DIFFERENT CONFINEMENT CONDITIONS Kıyıcı, Fırat; Perçin, Mustafa; Department of Aerospace Engineering (2022-7-27) In modern gas turbine combustors, flame stabilization is achieved by use of swirlers which introduce swirl component to the flow field. Swirlers are inherently sensitive to flow and environmental conditions, and even a minor geometrical modification can change the flow field remarkably. One of the critical parameters that affect the performance of the swirler is the channel orientation of the swirler channels. In the literature, the channel orientation has been mostly investigated at constant confinement ra...
Kinetic analysis of crude oils by a weighted mean activation energy approach Kök, Mustafa Verşan (1997-01-01) A weighted mean activation energy method was applied to describe the reactivity and combustibility of crude oils via simultaneous TG/DTG. Thermal experiments were conducted with a non-isothermal method at a heating rate of 10 degrees C min(-1) with excess air. Reaction rates increased progressively with increasing temperature. The rate data were fitted to an Arrhenius equation; the plots showed three distinct reaction regions. Weighted mean activation energies (E(wm)), of the crude oils were calculated and ...
Thermodynamic analysis of plasma-assisted reforming of methane Maşera, Kemal; Taylan, Onur; Sustainable Environment and Energy Systems (2016-6) Conventional techniques of syngas production use the exhaust gas of combustion of fossil fuels or feedstock like biomass itself. High temperatures are required for this process. To achieve necessary high temperatures, about 30% of feedstock is used initially. Another disadvantage of these conventional techniques is the tar formation which can damage the system by blocking the equipment. On the other hand, plasma processes are more efficient techniques to convert energy like solar, electrical, etc. int...
Coating of iron oxide pellets for direct reduction Basdag, A; Arol, Ali İhsan (2002-06-01) Depending upon their chemical composition and, to a lesser extent, on their physical properties, iron oxide pellets exhibit varying degrees of sticking tendency during direct reduction at elevated temperatures. For an efficient shaft furnace operation in direct reduction (DR), it is imperative to prevent pellets from sticking to each other and, hence, forming clusters. Coating of pellets with a suitable inorganic material has increasingly been gaining recognition amongst the pellet producers and DR plant op...
