Experimental investigation of heat transfer characteristics and wall pressure distribution of swirling coaxial confined impinging air jets
(Pergamon-Elsevier Science Ltd, 2018)In the present study, swirling coaxial confined impinging turbulent air jets issuing from a novel designed nozzle is studied experimentally. Heat transfer characteristics and pressure distribution on the impingement plate ... -
Experimental study of single-phase fluid flow and heat transfer characteristics in rectangular microchannels
(2018)In this study, single-phase laminar flow of deionized water through microchannel heat sinks is investigated experimentally. Heat sinks including twenty-nine parallel rectangular channels have been used as the test samples. ... -
Latest Cretaceous "A(2)-type" granites in the Sakarya Zone, NE Turkey: Partial melting of mafic lower crust in response to roll-back of Neo-Tethyan oceanic lithosphere
(Elsevier Science Bv, 2018)An integrated study of comprehensive geochronological, geochemical, and Sr-Nd-Hf isotopic data was undertaken for the A-type Topcam pluton that intruded within the Sakarya Zone (NE Turkey) with the aims of elucidating its ... -
Exergetic performance comparison of air and hydrogen gas flowing through the annular curved duct
(Pergamon-Elsevier Science Ltd, 2018)The main objective of this study is to parametrically compare the exergetic performance of air and hydrogen gas flow through the curved annular duct. For this purpose, it is assumed that, i) air and hydrogen are considered ... -

Magnetic features of boron doping on Hf2Co11 thin films
(Springer, 2018)The effect of boron (B) doping on the structural and magnetic properties is studied systematically in the Hf2Co11 thin films. the modified crystal microstructure and annealing process enhanced the coercive field up to 1754 ... -
Comparing the pozzolanic activity properties of obsidian to those of fly ash and blast furnace slag
(Elsevier Sci Ltd, 2018)The use of pozzolan in cement provides economic advantages and improves the physico-mechanical properties of cement. Fly ash and blast furnace slag are widely used in cement as pozzolanic materials. in this study, obsidian ... -
Magnetic energy conversion
(Elsevier Inc., 2018)In this study, magnetic and electromagnetic energy conversion of magnetocaloric materials (MCMs) and magnetic refrigeration, which is based on magnetocaloric effect (MCE), is presented in detail and made apprehensible. The ... -
Age constraints on intra-formational unconformities in Upper Jurassic-Lower Cretaceous carbonates in northeast Turkey; geodynamic and hydrocarbon implications
(Elsevier Ltd, 2018)Upper Jurassic-lowermost Cretaceous carbonate build-ups are imaged on seismic data in the Black Sea. They form important, untested, hydrocarbon reservoirs that are the focus of active exploration. Outcrop analogues to these ... -
