Exergy destruction analysis of a gas turbine power plant
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2018)
According to the data released by “Republic of Turkey-the Ministry of Energy and Nat ural Resources”, by the end of July 2017, 34% of the electricity of Turkey was produced from natural gas. As it is compared to ...
Effect of tooth profile modification on wear in internal gears
(IOP Publishing Ltd, 2018)
Internal gears are often used in the automotive industry when two gears are required to rotate in the same direction. Tooth shapes, slippage speeds at the beginning and end of meshing are different according to the external ...
Heat transfer enhancement methods: Concave and convex shape fins
(Avestia Publishing, 2016)
The heat transfer coefficient is a common engineering concept and a significant number of researchers are focusing on improving the heat transfer performance of the system by increasing the heat transfer coefficient. Heat ...
Quasi-static axial crushing behavior of thin-walled circular aluminum tubes with functionally graded thickness
(Elsevier Ltd, 2016)
In this paper, the crushing behavior of circular aluminum thin-walled tubes with functionally graded thickness (FGT) are investigated experimentally. To this aim, three different thickness grading patterns are introduced ...
Effects of holding force on the springback behavior of annealed aluminum plates
(Elsevier Ltd, 2016)
Typical V-bending process was performed to investigate the effects of holding force on springback behavior of 1050-H14 aluminum alloy plates annealed at 120 °C for 20 minutes. Tests were conducted on a universal testing ...
Stress analysis of functionally graded disc under thermal and mechanical loads
(Elsevier Ltd, 2011)
In this study, the elastic stress analysis of annular discs made of functionally graded materials (FGMs) subjected to both uniform pressures on the inner surface and a linearly decreasing temperature distribution has been ...
Numerical investigation of heat transfer using impinging jets on triangular and square ribbed roughened walls
(Turkish Society for Thermal Science and Technology, 2017)
This paper presents a heat removal study on triangular and square ribbed surfaces under an array of impinging air jets. The investigation was carried out using nozzles with a 7x3 rectangular array of circular jets. The ...
Second law analysis of different refrigerants in a two stage vapor compression cycle
(Turkish Society for Thermal Science and Technology, 2015)
In this study, the second law analysis has been made by means of the program developed using the software program EES (EES-V9.172-3D) in a two stage vapor-compression refrigeration cycle for the refrigerants such as R600 ...
Comparison of superheating effect of water as a refrigerant with the other refrigerants
(2011)
The performance comparison of water as a refrigerant (R718) with some refrigerants including R717, R290, R134a, and R152a is presented for a vapor compression refrigeration cycle. A computer program simulating the vapor ...
Çarpan akışkan jetleri kullanarak kanatçıklı yüzeyler üzerindeki akış alanının sayısal olarak incelenmesi
(Ahmet Yesevi Üniversitesi, 2017)
Bu çalışmada, 7x3 olarak dikdörtgen dizilime sahip dairesel jetler kullanılarak üçgen ve kare kanatçık bulunan yüzeyler üzerine çarptırılması sonucu oluşan akış yapısı sayısal olarak incelenmiştir. Re sayısının, jet-plaka ...
