A dynamic model of air-breathing polymer electrolyte fuel cell (PEFC): A parametric study
(Elsevier, 2021)
A dynamic model for an air-breathing PEFC has been built to investigate the transient response of the fuel cell to load changes. The sensitivities of the dynamic response, as well as the steady state performance, to: the ...
Evaluation of regional climate models ALARO-0 and REMO2015 at 0.22° resolution over the CORDEX Central Asia domain
(Copernicus Publications, 2021)
To allow for climate impact studies on human and natural systems, high-resolution climate information is needed. Over some parts of the world plenty of regional climate simulations have been carried out, while in other ...
Modulation of Charge Transport at Grain Boundaries in SrTiO3: Toward a High Thermoelectric Power Factor at Room Temperature
(American Chemical Society, 2021)
Modulation of the grain boundary properties in thermoelectric materials that have thermally activated electrical conductivity is crucial in order to achieve high performance at low temperatures. In this work, we show ...
Thermal analysis and wear behavior of shell mold cast and graphite mold cast Mg-4Zn-(x)Zr alloys
(CSIC Consejo Superior de Investigaciones Cientificas, 2021)
The grain refining effect of Zirconium (Zr) is known, nevertheless the effect of Zr amount and its effect on solidification and wear behavior of modified Mg-Zn alloys has not been adequately studied. Mg-4Zn-(x)Zr alloys ...
Yeraltı suyu seviye değişiminin M5 karar ağacı ve yapay sinir ağları yöntemleriyle belirlenmesi
(İskenderun Teknik Üniversitesi / Lisansüstü Eğitim Enstitüsü / İnşaat Mühendisliği Ana Bilim Dalı, 2021)
Bu çalışmada, bağımlı değişken yeraltı suyu seviyesi (YASS) ve bağımsız değişkenler olarak da yağış, sıcaklık ve önceki günkü yeraltı suyu seviyesi kullanıldığı bir stokastik modelle yeraltı suyunun davranışı araştırılmıştır. ...
Effect of thermal degradation on the properties and wear behavior of Cr−V−C composite coatings grown on ductile iron
(Elsevier, 2021)
The thermal fatigue behavior of chromium vanadium carbide (Cr - V - C) coatings and the wear of the coatings after thermal fatigue cycling was studied. The Cr - V - C coatings were grown on the surface of a ductile iron ...
Türkiye'deki iklim değişikliği ve yağış dağılışının hidroelektrik enerji kazanımı üzerindeki etkileri
(İskenderun Teknik Üniversitesi / Lisansüstü Eğitim Enstitüsü / Enerji Sistemleri Mühendisliği Ana Bilim Dalı, 2021)
Gün geçtikçe artan Dünya nüfusu ve ardından gelen tüketim isteğine bağlı üretim, iklim değişikliğini beraberinde getirmektedir. Alışılagelmiş Türkiye iklimindeki değişimlerle son yıllarda atmosferde oluşan tahribatın ...
The investigation of microstructure and high temperature mechanical properties of novel Mg-Al-Sn-Ce alloy produced by HPDC
(Taylor and Francis, 2021)
Different weight ratios of cerium (0.5, 1 and 2 wt.%) were produced in a controlled atmosphere by High Pressure Die Cast method to Mg-6Al-0.3Mn-1Sn alloy. The influence of cerium on microstructure and high-temperature ...
Optimisation of simple and regenerative organic Rankine cycles using jacket water of an internal combustion engine fuelled with biogas produced from agricultural waste
(Elsevier, 2021)
Internal combustion engines have a very important place in biogas production facilities to convert biogas energy to electricity. Unfortunately, although intense studies on improving internal combustion engine efficiencies ...
A comprehensive comparative energy and exergy analysis in solar based hydrogen production systems
(Elsevier, 2021)
In the presented paper, energy and exergy analysis is performed for thermochemical hydrogen (H2) production facility based on solar power. Thermal power used in thermochemical cycles and electricity production is obtained ...
