Effects of main transformer replacement on the performance of an electric arc furnace system
Akdag, A; Cadirci, I; Nalcaci, E; Ermiş, Muammer; Tadakuma, S (2000-03-01)
In this paper, the effects of transformer replacement on the electric are furnace power system of an iron and steel plant have been investigated. The new operating strategy has been determined according to stable are and maximum productivity requirements. Based on these new operating conditions, the sufficiency of the existing flicker compensation system in terms of the load balancing, power-factor correction, and flicker have been examined. All investigations made in this work are supported by real-time me...
Effects of Atmospheric Icing on Performance of Controlled Wind Turbine
Şahin, Mustafa (2022-03-18)
Icing deteriorates the performance of wind turbine rotors by changing the blade airfoils’ shapes. It decreases the lift, increases the drag, and subsequently causes power production losses and load increase on turbines’ structures. In the present study, the effects of atmospheric icing on the performance of a controlled large-scale wind turbine is estimated through simulations. To achieve the target, the MS (Mustafa Sahin) Bladed Wind Turbine Simulation Model is used for the analyses of the National ...
Effects of injection pressure and post-curing on the behavior of woven carbon fiber/epoxy composites produced by rtm (resin transfer molding)
Kaş, Yusuf Onur; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2002)
RTM (Resin Transfer Molding) is a closed mold process in which matrix resin is injected into a mold filled with a fiber preform. There are many RTM process parameters influencing the quality of the final product. The objective of this work was to study two of these variables: resin injection pressure and post-curing conditions. For this purpose, an amine curing epoxy resin was injected, by using a small laboratory size RTM machine, into a flat mold filled with woven carbon fiber layers. Various combinations...
Effects of silica nanoparticles on the performance of water-based drilling fluids
Kök, Mustafa Verşan; Bal, Berk (2019-09-01)
In this research, two groups of experiments were conducted to investigate the effects of silica (SiO2) nanoparticles on the filtration and rheological properties of water-based drilling fluids. In the first group, bentonite, chrome-free lignosulfonate (CFL) and carboxymethyl cellulose (CMC) were used in different concentrations to obtain base fluids. Nanofluids were prepared by adding 0.5 g of four different silica nanoparticles into these drilling fluids. Comparison of rheological properties, fluid loss am...
Effects of cyclic strain hardening on performance of eccentrically braced frames
Balıkçı, Elif Müge; Topkaya, Cem (2021-12-01)
Performance based seismic design (PBSD) procedures have been developed in recent years. Studies conducted in the past revealed that strain hardening ratio (SHR) used in numerical modeling can be influential on the performance of steel structural systems. In this paper, the effects of SHR on the performance assessment of eccentrically braced frame (EBF) buildings were studied by using FEMA P-58 methodology. The numerical model was validated using the pseudo-dynamic test results of the DUAREM structure. Seism...
