Grain Refinement, Modification, Degassing and Melt Quality Relationship in Al-7Si-0.3Mg
(2014-01-01)In this work, Al-7Si-0.3Mg alloy was studied. The alloy conditions was selected to be as-received, AlB3 grain refined and Sr modified. For each parameter, castings were made before and after degassing. In order to quantify ... -
Jeotermal ısı kaynaklı Organik Rankine Çevriminde kuru ve izantropik akışkanların çevresel etkilerinin ve termodinamik performanslarının karşılaştırılması
(GUFBD / GUJS Gümüşhane Üniversitesi FBD, 2022)Organik Rankine Çevrimi (ORÇ), düşük sıcaklık aralığında su yerine organik akışkanın kullanıldığı bir elektrik üretim sistemidir. ORÇ, elektrik üretmek için atık ısıyı değerlendirmek amacıyla santrallerde kullanılmaktadır. ... -
Methyl methacrylate in external fixation of supracondylar humerus fractures: An experimental study
(Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2018-08-24)Supracondylar humerus fractures are common fractures around the elbow. Open fractures, comminuted metaphyseal fractures and also fractures with bone loss may need to be treated with external fixators. The aim of this study ... -
Optimization of secondary cooling percentage during semi-continuous copper casting process
(Begell House, Inc., 2017-02-16)Sufficient cooling is essential to reduce casting defects and to get high productivity in semi-continuous casting of copper billet. On the other hand, low rate solidification is desired in order to develop coarser grain ... -
ORÇ ile Düşük Sıcaklıklı Isı Kaynaklarından Elektrik Üretilmesinde Islak ve Yeni Nesil Akışkanların Çevresel ve Termodinamik Performanslarının Karşılaştırılması
(NEÜ FMBD, 2021)Organik Rankine Çevrimi (ORÇ), termal enerjiyi elektrik enerjisine dönüştüren, yüksek oranda erişilebilir, yaygın olarak kullanılan bir enerji üretim şeklidir. ORÇ’de, türbin jeneratörü termal enerjiyi önce mekanik ... -
Prediction and sensitivity analysis under different performance indices of R1234ze ORC with Taguchi’s multi-objective optimization
(Case Studies in Thermal Engineering, 2020)In this study, parametric optimization and sensitivity analysis of performance parameters were performed for the Organic Rankine Cycle (ORC) system at 120 °C heat source temperature. R1234ze, which is called the new-generation ... -
Study Gas Flow Heating In Micro-Nozzle Through Walls Instead Of Preheating
(2016-07)Previously, Preheating has been established in micro-nozzles to increase the specific impulse of thrusters and increase thrust level. However, heating may cause higher viscous losses in micro-nozzles working at low Reynolds ...
