Yalıtımlı dış duvarlarda kullanılan sentetik emülsiyon, polimer ve çimento esaslı koruyucu dış cephe kaplamaları ve bunları tamamlayan alt katmanların oluşturduğu dış cephe bitirme sistemleri, su buharı geçirimliliği ve esneklik modülü açısından incelenmiştir. Astar, boya ve ısı yalıtım katmanları gibi yalıtımlı dış duvar kesitini tamamlayan diğer katmanların da su buharı geçirimlilikleri incelenmiştir. Yapı bileşenlerini oluşturan malzemelerin tek başlarına özellikleri önemli olmakla birlikte, ilişkide oldukları diğer komşu malzemelerle de uyumluolmaları önemlidir. İncelenen tüm cephe kaplamalarının yüksek su buharı geçirimliliğine sahip oldukları anlaşılmıştır. Gerçekte su buharı geçirimliliğine direnç indeksi (μ) yüksek olan bu kaplamalar, çok ince tabakalar halinde uygulandıklarından dolayı, yüksek su buharı geçirimli hale gelmişlerdir. Astar veya boya katmanı, cephe kaplama malzemelerinin nefes alma özelliklerini değişen seviyelerde azaltmaktadır. Polistiren ısı yalıtım malzemeleri ile çimento esaslı kaba ve ince sıvalar, duvar kesiti içerisindeki su buharı akışını önemli ölçüde kesen, yani duvarların nefes almasına engel olan katmanlardır. Sentetik emülsiyon ve çimento esaslı cephe kaplamalarının ve bunlarla birlikte kullanılan çimento esaslı sıvaların düşük ama yeterli bir dayanıma sahip oldukları görülmüştür.

OPTIMAL BATTERY SIZING FOR ELECTRIC VEHICLES CONSIDERING BATTERY AGEING TO MINIMIZE THE TOTAL COST OF THE POWER TRAIN COMPONENTS AND CONSUMED ENERGY Gezer, Ali; Ünver, Baki Zafer; Department of Electrical and Electronics Engineering (2021-8-04) Due to environmental issues such as emission of carbon gases, massive energy consumption, depleting natural resources regarding the internal combustion engine (ICE) based vehicles, electric vehicles (EVs) have caught more and more attention. To make EVs feasible and common, the batteries' high cost and performance degradation problems have to be overcome. The degradation of the battery regarding both energy capacity and power capability is highly dependent on conditions of utilization. Inspired by the liter...
Optimization of nickel, cobalt and lithium recovery processes from spent li-ion batteries Tekmanlı, Fırat; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-12-28) Since lithium-ion batteries are standard in electric vehicles and electrical devices and have the potential to be used widely in the future, it is essential to recycle end-of-life batteries. Waste lithium-ion batteries are harmful to the environment and human health and should be recycled also due to their critical metals. Lithium-ion batteries can be classified according to their cathode chemistry. In this thesis, the recycling of lithium-ion batteries with NMC-type (Nickel- Manganese-Cobalt) cathode chemi...
Investigation of variations in performance properties of asphalt concrete using image-based finite element model Karakaya, Yalçın; Güler, Murat; Department of Civil Engineering (2022-7-20) The objective of this study is to evaluate variations in performance properties of asphalt concrete using a two-dimensional image-based finite element model. Two different asphalt mixtures are used in both laboratory tests and in FEM analyses representing different conditions. A flatbed scanner is then used to capture cross-sectional images of the samples and various image processing techniques are applied to prepare the images for FEM. A unique image vectorization method has been developed to transform cro...
Feedback motion planning of a novel fully actuated unmanned surface vehicle via sequential composition of random elliptical funnels Özdemir, Oğuz; Ankaralı, Mustafa Mert; Department of Electrical and Electronics Engineering (2022-12-27) This thesis proposes and analyzes a motion planning and control schema for unmanned surface vehicles that fuses sampling-based approaches’ probabilistic completeness with closed-loop approaches’ robustness. The Proposed schema is based on the sequential composition of elliptical funnels, and it consists of two stages: tree generation and motion control. For validation of the approach, we carried out experiments using both simulation and physical setup besides the mathematical analysis. In order to have a co...
Investigation of Droplet Flame Interactions through Experimental and Numerical Approaches Kaya Eyice, Deniz; Yozgatlıgil, Ahmet; Aksel, M. Haluk; Department of Mechanical Engineering (2023-1-12) Spray combustion applications involve complex phenomena such as atomization, droplet vaporization, mixing, turbulence, chemical kinetics, and the interaction of these processes. In two-phase combustion, one of the fundamental processes is the interaction of a single droplet with a flamelet. Therefore, it is essential to understand the physics of isolated droplet evaporation and its effects on the flame front to study more complex flames. The aim of this study is to investigate droplet evaporation, flame ch...
