T-şekilli kanat geometrilerinin ısı transfer oranı arttırımındaki ektileri

Thesis (Master)--Izmir Institute of Technology, Mechanical Engineering, Izmir, 2017Includes bibliographical references (leaves: 37-38)Text in English; Abstract: Turkish and EnglishIn this study, we show that maximum excess temperature on a heat generating cylindrical solid domain can be minimized with numerically optimized rectangular cavities and T-shaped fins. The effects of the cavities and the fins on heat transfer rate enhancement were compared while their volume fractions in a unit volume element were fixed. Furthermore, the designs correspond to the minimum thermal resistance were uncovered for two types of flows; parallel and cross-flow. The governing equations of the heat transfer and the fluid flow were solved simultaneously in order to show the effects of flow characteristics and the design on the thermal performance. Two-dimensional solution domain was used to uncover the thermal performance in cross-flow case. Because the flow direction is perpendicular to the heat transfer surface area of the heat generating domain. However, three-dimensional domain was used in parallel flow case because the fluid flows along the outer surface of the heat generating domain and the heat transfer surface area. For the cross-flow case, the results show that T-shaped assembly of fins with longer stem and shorter tributaries corresponds to thelower peak temperature. In addition, the results also show that there is an optimal cavityshape that minimizes the peak temperature. This optimal shape becomes thinner when thenumber of the cavities increase. In parallel flow case, fins with thicker and shorter stemand longer tributaries corresponds to the minimum excess temperature. In addition, longand thin cavity shapes increase the thermal performance in parallel flow case.Bu çalışmada ısı üretimli silindirik bir katı bölgede biriken maksimum sıcaklığın sayısal olarak optimize edilmiş dikdörtgen kaviteler ve T şekilli kanat montajı ile minimize edilebileceği gösterilmektedir. Kavite ve kanatların ısı transfer oranı arttırımındaki etkileri birim hacim içindeki oranları sabit tutularak karşılaştırılmıştır. Ayrıca parallel ve zıt akış olarak iki tip akış tipinde minimum ısıl direnc elde edilen tasarımlar bulunmuştur. Isı transferi ve akış denklemleri, akış karakteristiği ve tasarımdaki değişimlerin performans üzerindeki etkilerini göstermek için eşzamanlı olarak çözülmüştür. Zıt akış durumunda, akışın ısı üretimli bölgenin ısı tansferinin gerçekleştiği yüzey alanına dik gelmesinden dolayı çözümlemeler 2 boyutlu model üzerinde yapılırken, paralel akışlı durumda ise akışkan hareketinin ısı üretimli bölgenin dış yüzeyi ve toplam ısı transfer yüzey alanı boyunca olmasından dolayı 3 boyutlu model üzerinde yapılmıştır. Zıt akışlı durumda, daha düşük maksimum sıcaklığa sahip kanat tasarımlarının uzun saplı ve kısa dallanmalı olduğu sonucuna ulaşılmıştır. Ayrıca, yapılan analizler termal performansı daha iyi olan optimum bir kavite geometrisinin olduğunu göstermektedir. Bu kavite geometrisi kavite sayısı arttıkça daha dar bir yapıya bürünmektedir. Paralel akışlı durumda ise daha kalın ve kısa saplı, uzun dallanmalı kanat tasarımları ısıl direnci düşürmekte iken kavite modellerinde bu durum daha uzun ve ince kavite tasarımları ile sağlanmaktadır

The effect of cavities and T-shaped assembly of fins on overall thermal resistances

In this study, authors show that maximum excess temperature on a heat generating cylindrical solid domain can be minimized with numerically optimized rectangular cavities and T-shaped fins. The effect of the cavities and the fins on overall thermal resistances were compared while their volume fraction in a unit volume element is fixed. Furthermore, the designs correspond to the minimum thermal resistance were uncovered for two types of flows; parallel and cross-flow. The governing equations of the heat transfer and the fluid flow were solved simultaneously in order to show the effects of design on the flow characteristics and the thermal performance. Two-dimensional solution domain was used to uncover the thermal performance in cross-flow case because the flow direction is perpendicular to the heat transfer surface area of the heat generating domain. However, three-dimensional domain was used in parallel flow case because the fluid flows along the outer surface of the heat generating domain. For the cross-flow case, the results show that T-shaped assembly of fins with longer stem and shorter tributaries correspond to the lower peak temperature. In addition, the results also show that there is an optimal cavity shape that minimizes the peak temperature. This optimal shape becomes thinner when the number of the cavities increase. In parallel flow case, fins with thicker and shorter stem and longer tributaries correspond to the minimum excess temperature. In addition, the longer and thinner cavities increase the thermal performance in parallel flow case

Psychopathology, quality of life, and related factors in children with celiac disease

Objective: This study aimed to survey children with celiac disease (CD) for psychiatric disorders, determine the possible factors that predict psychopathology, and analyze health‐related quality of life and possible factors that could affect the quality of life. Methods: In this study, all children completed the Schedule for Affective Disorders and Schizophrenia for School Age Children–Present and Lifetime Version–Turkish Version (K‐SADS‐PL‐T), as well as the Pediatric Quality of Life Inventory (PedsQL) for the 8–12 age group, and a sentence completion test. A face‐to‐face interview was performed with the parents of the participants to inform them about the study. Results: This study included 52 children with celiac disease in the age range of 8–12 years, and 40 healthy children. The mean age of the study group was 10.36 ± 0.36 years, and 31 (59%) of them were females. The mean age of the control group was 10.35 ± 0.46 years and 24 (60%) of them were females. The mean subscale scores of the Pediatric Quality of Life Inventory were significantly lower in children with celiac disease when compared to the control group (p < 0.05). There was at least one psychiatric disorder in the 26 (50%) children with celiac disease. Conclusions: This study has shown once more that celiac disease is associated with some psychiatric signs/diagnoses, and that it decreased quality of life. Further studies are needed to determine the factors that could reduce the psychiatric signs. It is apparent that those studies would contribute new approaches to improve diagnosis, treatment, and quality of life

Air-water exchange of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) at a coastal site in Izmir Bay, Turkey

The air-water exchange of polychlorinated biphenyl (PCB) and organochlorine pesticides (OCPs) were investigated using paired air-water samples (n = 16) collected in July and February-March, 2005 from Guzelyali Port in Izmir Bay, Turkey. Atmospheric PCBs and OCPs were mainly in gas-phase in both periods. However, their dissolved and particle-phase water concentrations were comparable. For PCBs, 3 and 4-Cl congeners were dominant while chlorpyrifos, endosulfans and HCHs were the most abundant OCPs for all samples. Especially in summer, calculated net gas-exchange PCB fluxes were mainly volatilization from the water ranging from - 0.2 (volatilization, PCB-101) to - 30.0 (volatilization, PCB-31) ng m- 2 day- 1. For OCPs, net flux ranged from - 0.03 (volatilization, cis-nonachlor) to 1568 (deposition, endosulfan I) ng m- 2 day- 1 and they have seasonal variations with generally deposition in winter and volatilization in summer. However, endosulfan I, II, endosulfan sulfate, α- and γ-HCH deposited in both periods. The calculated residence times of PCBs and OCPs in the water column indicated that the gas-exchange in the Bay is at least as or a more important mechanism than advection. Annual gaseous absorption and volatilization fluxes were calculated and were used along with the estimated dry deposition fluxes and wet deposition fluxes measured recently at a suburban site in Izmir to determine the relative contributions of different atmospheric mechanisms to the pollutant inventory of the Bay water column. Results suggested that the relative contributions of all studied mechanisms to the water column PCB and OCP inventories were significant.Dokuz Eylul University (Project No:03.KB.FEN.101); TÜBİTAK (Project no.
