ÜÇGEN KAPALI ORTAMDA DÜŞEY YÜZEYE YERLEŞTİRİLEN ENGEL EĞİMİNİN DOĞAL TAŞINIMLA ISI TRANSFERİ ÜZERİNE ETKİSİNİN SAYISAL OLARAK İNCELENMESİ
(11. ULUSAL TESİSAT MÜHENDİSLİĞİ KONGRESİ TESKON2013, 2013-04-17)
Bu çalışmada, yalıtılmış düşey yüzeyine engel yerleştirilen üçgen şeklindeki çatı içerisinde doğal taşınımla ısı transferi sayısal olarak incelenmiştir. Üçgen kapalı ortamın tabanı eğimli yüzeyden daha sıcak olup, düşey ...
Effect of Working Conditions on the Lubricated Wear Behavior of Zn-40Al-2Cu-2Si Alloy in the As- Cast and T6 Heat-Treated States
(American Society of Mechanical Engineers (ASME), 2022)
In order to determine the effect of working conditions on the lubricated wear behavior of Zn-40Al-2Cu-2Si alloy in the as-cast and T6 heat-treated states, its tribological properties were studied at different oil flowrates, ...
Effect of Plastic Deformation on the Mechanical Properties of Dual-Phase Steels Using Nanoindentation
(Springer, 2023)
The mechanical properties of two advanced high-strength steels (AHSS), DP 1000 and DP 1200 dual-phase (DP) grades, under deformed and undeformed conditions, were investigated using nanoindentation, and the results were ...
Energy and economic assessments of waste heat recovery by designs of economizer, condensing economizer and air preheater
(Gazi Universitesi, 2023)
In this study, the waste heat loss of flue gases from the boilers of Kafkas University district heating system has been calculated between 6-8% according to the combustion analysis and the annual cost of this heat loss has ...
High-cycle fatigue and tensile strength of AZ91 Mg alloy with MAO-epoxy duplex coating
(Institute of Materials and Machine Mechanics, 2023)
In this study, an epoxy layer was formed by the immersion process, on the oxide layer grown by the micro-arc oxidation (MAO) treatment of the AZ91 magnesium alloy, using the thin film sealing technology, and its effect on ...
Enhanced wear resistance and surface properties of oxide film coating on biocompatible Ti45Nb alloy by anodization method
(Elsevier B.V., 2023)
β-Titanium alloys have become increasingly popular as biomaterials because of their low modulus of elasticity and superior corrosion properties in recent years. β-titanium alloy containing niobium is also a biocompatible ...
Gyroscopic suspension for a heavy vehicle
(Inderscience Publishers, 2023)
In this study, an angular momentum generated by a flywheel gyroscope is performed as a suspension to prevent vehicle vibration. The frequency equations are derived and the optimal flywheel speed is obtained for vibration ...
The Effect of Surface Roughness on Fatigue Life in AZ31 Magnesium Alloy
(Springer, 2023)
Magnesium alloys have excellent properties such as high specific strength, rigidity, good damping, electromagnetic shielding, castability, and machinability. However, corrosion, creep, and fatigue resistance are generally ...
Effect of Isothermal Treatment on Mechanical and Tribological Properties of Alloy Zn – 40% Al – 2% Cu – 2% Si
(Springer, 2023)
The effect of isothermal exposure at temperatures from 100°C to 250°C for 8 hours on the structure, mechanical and tribological properties of the Zn – 40% Al – 2% Cu – 2% Si alloy produced by chill casting is studied. The ...
Wear Behavior of Dental Restorative Materials
(CHINESE SOC MECHANICAL ENGINEERS, 2023)
Gradual wear of opposing teeth is a normal phenomenon in human dentition. There is a need for quality dental restorative materials to repair or replace natural teeth to ensure a higher quality of life through dental health. ...
