ENERGY, EXERGY ANALYSIS AND OPTIMIZATION OF INSULATION THICKNESS ON BUILDINGS IN A LOW-TEMPERATURE DISTRICT HEATING SYSTEM
(YILDIZ TECHNICAL UNIV, 2023)
In the study, energy and exergy analysis of the buildings on a campus in Turkey are conducted by using actual operating data and taking measurements in the district heating system as a case study. The energy and exergy ...
Investigation of used PCM-integrated into building exterior walls for energy savings and optimization of PCM melting temperatures
(Elsevier Ltd, 2023)
In the study, the effects on the building's thermal energy performance of using two different phase change materials (PCMs) integrated into the exterior walls at various thicknesses and melting temperatures have been ...
Comparison of Mechanical Properties Obtained for Armor Steels: Conventional Methods vs. Nanoindentation
(ASTM International, 2023)
The mechanical properties of three armor steels, namely Ramor 500, Ramor 550, and Armox Advance, were acquired by nanoindentation and conventional methods, and then the results were compared. To this goal, samples were ...
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 ...
