Bu çalışma yüksek sıcaklıktaki suyun göl ve rezervuar gibi akıntısız su kütlelerine verilmesini incelemektedir. Sayısal çalışmada PROBE isimli bir boyutlu (1B) sonlu hacim yazılımı kullanılmıştır. Yazılım, yüksek sıcaklıktaki suyun ve rüzgârın göl içindeki karışma süreçlerine etkisine, Koriolis etkisine ve güneş ışınımı etkisine açıklamalar getirmektedir. Bu koşullar termik santrallerdeki (kömür, doğalgaz, nükleer vb.) soğutma işlemleriyle alakalıdır. Mevsimsel doğal tabakalaşma ve termoklin oluşumu sayısal yöntemlerle ışık geçirim katsayısı, güneş ışınımı ve rüzgâr hızı kalibre edilerek gerçek bir göl için elde edilmiştir. Yapay bir göle su girişinde ve gölden su çıkışında oluşan termal tabakalaşma birçok durum için çalışılmıştır. Çalışma, yapay gölde, su giriş ve çıkışının kısa dalga ışınımı ve rüzgâr etkisi ile beraber düşey termal profile yaptığı etkiyi bir günlük (24 sa.’lik) süre için incelemektedir. 24 sa.’lik sonuçlar ortalama bir işlemci ve bilgisayar kullanılarak dakikalar içinde elde edilmiştir. Bu daha uzun vadedeki sonuçların kısa sürede elde edilebileceğini göstermiş ve bu tür kodların termal mühendislik uygulamalarında ne kadar kullanışlı olduğunu ortaya koymuştur

Thermal network method applications to problems related with the thermal analysis of small satellites. Okan, Altuğ; Çelenligil, M. Cevdet; Tekinalp, Ozan; Department of Aeronautical Engineering (2002) In this thesis, the thermal network method is examined in detail and is applied to some problems related with the thermal analysis of small satellites. In satellites, dominant modes of heat transfer are the thermal radiation and conduction. In this research, energy exchanges among the surfaces of satellites are investigated. Also, the radiation exchange factors are determined which are necessary in radiation thermal analyses. A FORTRAN code 'TRANS" is developed. This code uses the thermal network method for...
Thermal performance enhancement of microencapsulated phase change material/geopolymer composites through graphite platelets and nano-additives for building energy storage applications Tolga , Tamer; Akgül, Çağla; Baker, Derek Keıth; Department of Micro and Nanotechnology (2023-1) The demand for sustainable, low-energy buildings with minimized operating costs is increasing. Meeting this ever increasing demand while providing sufficient occupant thermal comfort is a challenge. In the recent years, solutions that try to utilize the thermal energy storage potential of the building envelope are being developed at a rapid pace. Combining the high storage capacity of micro-encapsulated phase change materials (mPCM) with high thermal conductivity waste materials lead to sustainable, low-car...
Thermal rectification behaviour of some small quantum systems Zervent, Selahittin Atılay; Turgut, Sadi; Department of Physics (2021-9-10) Thermal rectification behaviors for some small quantum systems are studied by using the Lindblad master equation. From the underlying Hamiltonian dynamics of the composite quantum systems consisting of small quantum systems and reservoirs, Lindblad master equations are obtained by using certain approximations. Optimum operation parameters are determined for a single two-level and two two-level quantum systems. It is shown that there is no thermal rectification behavior when the contact between two reservoir...
Energy conscious machine and robot speed decisions in two machine robotic cell scheduling Güzel, Betül Necibe; Gürel, Sinan; Department of Industrial Engineering (2021-6-15) Minimizing cycle time has always been a critical objective in manufacturing cells. Recently, energy efficient and environmentally conscious manufacturing practices have received increasing attention from researchers and practitioners. Therefore, in this thesis we consider a 2-machine manufacturing cell with a material handling robot where two conflicting objectives exist: minimization of cycle time and energy consumption. It is a flow type cell where identical parts are first processed on the first machine ...
THERMAL BUCKLING OF LAMINATED PLATES WITH VARIABLE FIBER VOLUME FRACTION Mercan, Emrullah; Dağ, Serkan; Department of Mechanical Engineering (2023-1) This study investigates the stability of the graded fiber reinforcement composite plate under temperature-induced loads. The materials that make up the graded fiber reinforcement composite plate are fiber and matrix with different mechanical properties. Graduation is achieved by varying the volume fractions of the components across the thickness. The symmetric and unsymmetric ply sequences in the modeled composite plate are examined separately. Governing equations of motion and boundary conditions are obtai...
