Due to the complex nature of flow within a compressor, two- and three-dimensional CFD codes are commonly employed in compressor design today and they are leading to levels of efficiency believed to be impossible a few years ago. However, these sophisticated CFD codes are costly and time-consuming. Many improvements can be done in a simple mean-line analysis during the preliminary design of a compressor which leads to fewer hours of fine tuning in CFD codes. Despite its inherent limitations, the one-dimensional flow analysis along a mean-line is a very practical and powerful tool to inexpensively design and analyze a compressor. Mean-line method employs fundamental flow equations along with some empirical models to address the flow losses and some important flow phenomena. The accuracy of the results directly depends on the validity of the empirical models employed. The aim of this thesis is to develop a computer program that can be used to predict the performance of a radial compressor using mean-line method. Validation of the empirical models has been carried out by comparing the results with the experimental data available in the literature.

Development of an automatic design and analysis tool for axial compressors
Kündeş, Necmettin Anıl; Aksel, Mehmet Haluk; Baran, Özgür Uğraş; Department of Mechanical Engineering (2017)
In this thesis, an automatic design and analysis tool is developed for the design of an axial flow compressor and to check the required design conditions of the designed compressor by using three dimensional CFD analyses automatically. The developed tool mainly consists of six parts which are mean line design, calculations based on radial equilibrium theory, parametrization, generation of three dimensional blade geometry, mesh generation and solver. A new design study for an axial flow compressor begins wit...
Experimentation and optimization of a heat pump integrated dishwasher
Kütük, Erkan; Bayer, Özgür; Department of Mechanical Engineering (2019)
This study aims to develop the optimization of heat pump system working parameters for minimum energy consumption, operating time and noise level for a novel dishwasher. In an integrated heat pump system, compressor speed (N) and air flow rate (V̇) over the evaporator are selected as variables that affects energy consumption (E), acoustic level (A) and operating time (t). Due to the international energy regulations for household appliances, energy efficiency is highly important and for user comfort, operati...
A Computer vision based method for semi-automated rebar detection and measurement of reinforced concrete columns /
Hassan, Muhammad Usman; Kurç, Özgür; Department of Civil Engineering (2014)
As-built information of reinforced sections is necessary to ascertain structural characteristics from load carrying capacity, serviceability, structural integrity and adherence to code perspective. The objective of this research is to develop a semi-automated structural information acquisition method that can be used to determine as-built information regarding rebar grids of reinforced concrete columns. The technique involves application of photogrammetry, image processing and computer vision knowledge to o...
High performance macro synthetic fiber reinforced concrete
Öztürk, Çağrı; Yaman, İsmail Özgür; Department of Civil Engineering (2018)
Since concrete is a brittle construction material, it has the tendency to fail in a brittle manner after the occurance of the first crack when it is subjected to a certain amount of load. Therefore, this property of concrete makes almost impossible for it to be used in load carrying structural elements without reinforcement. This reinforcement is usually utilized by a structural steel reinforcement such as rebar and wire mesh. The structural steel reinforcements compensate the low resistance against the ten...
Behavior of FRP reinforced AAC structural elements
Tuncer, Ertürk; Binici, Barış; Department of Civil Engineering (2018)
AAC beams are classically manufactured by using steel reinforcement. However, in order to obtain more economical design and to prevent corrosion, it is also possible to apply FRP reinforcement. For this purpose, first, an experimental study was conduct-ed to investigate the response of steel reinforced and fiber reinforced AAC beam specimens under four point bending test. All the tests were performed with the col-laboration of Middle East Technical University and AKG Gazbeton. Unidirectional single layer ca...
