Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...
Experimental investigation of impinging jet array heat transfer from a surface with V-shaped and convergent-divergent ribs
(2012)
Detailed heat transfer measurements over a surface with V-shaped ribs (V-SR) and convergent-divergent shaped ribs (CD-SR) by a circular impinging jet array was investigated using thermal infrared camera. Both V-SR and CD-SR ...
Synthetic strategies towards the carbenoid reactions of α, β-acetylenic carbonyls
(TÜBİTAK, 2018)
Catalytic reactions of α, β-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated ...
An experimental study on the effects of diesel and jet-A1 fuel blends on combustion, engine performance and exhaust emissions in a direct injection diesel engine
(Turkish Society for Thermal Science and Technology, 2016)
In this study, an experimental investigation was performed in order to determine the effects of Jet-A1(A100), diesel fuel and Jet-A1/diesel fuel blends (A25, A50, A75) including 25% Jet-A1/75% diesel, 50% Jet-A1/50% diesel ...
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 ...
Pore modification in porous ceramic membranes with sol-gel process and determination of gas permeability and selectivity
(2010)
Summary: The aim of the study was to investigate the variation in total surface area, porosity, pore size, Knudsen and surface diffusion coefficients, gas permeability and selectivity before and after the application of ...
Abrasive wear, structure, and mechanical aspects of Al–Al2O3 composites fabricated using various mixing media during P/M routes
(Springer New York LLC, 2016)
The effects of mixing method during powder metallurgy (PM) routes on the abrasive wear behavior of Al–Al2O3p composite materials is investigated. For this purpose, starting Al powders with a constant volume fraction of 10% ...
Effects of nitridation time and precursor particle size on yield of β-SiAlON synthesized from calcined kaolinite
(Springer New York LLC, 2019)
Carbothermal reduction and simultaneous nitriding (CTRN) of natural aluminosilicates is a method used to obtain phases of Si–Al–O–N system. SiAlON phases have important applications, such as high technology ceramics, for ...
