Design, construction and performance evaluation of axial flow fans

Keklikoğlu, Hayrettin Özgür
The primary purposes of this study are to examine the methods used in axial flow fan design, to perform these methods on the design of an axial fan, to develop a design application in order to reduce the design errors and spent time in the design process, and to determine the reliability of the application with numerical and experimental methods. This study is concerned with the design of axial flow fans. It provides detailed information about the design process — additionally, a design code is implemented. All of the empirical data regarding axial fan design are digitized, and an airfoil database is generated in order to use in the code. In order to determine the pre-validity of the design code, computational fluid dynamics (CFD) methods are used. The aerodynamic characteristics of fans are examined in ANSYS CFX by using SST


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...

This paper presents a new design and analysis tool that is developed to be employed during the design process of axial flow compressors. The tool chain implemented by this design tool consists of five parts: a mean-line design tool, followed by a blade geometry parametrization tool. Then 3D blade geometry is created, next a high quality structured mesh is generated and completed by Computational Fluid Dynamics (CFD) solution. All components employed in the new tool are either new developments, or achieved b...
Dynamic stiffness-based test systems for viscoelastic material characterization: Design considerations
Özgen, Gökhan Osman; Batihan, Ali Cagri (2012-07-24)
In this paper, several important design issues for viscoelastic material characterization test systems which utilize dynamic stiffness measurements are discussed. These discussions are focused on structural dynamics aspects of the design of these test systems. These test systems are used to experimentally obtain the complex modulus of viscoelastic solids such as rubber, plastics, etc. Various standards exist on dynamic stiffness-based viscoelastic material characterization test methods, which give general g...
Design as a Collaborative Process A Systematic and Constructive Model for Developing Play Material for Blind Visually Impaired Preschool Children
Börekçi, Naz Ayşe Güzide Z. (2002-05-14)
This paper discusses a design process lived through, during the application of a model derived from design methodology and devised towards attaining a particular task. The task was: Designing a play system to contribute to the pre-school blind child’s development of object permanence, sense of self, and spatial concepts. The model employed was based on a systematic and constructive framework towards ensuring consciously made decisions. The paper also discusses the field-testing in play situations of the sys...
Design of a Test Setup for Measuring Dynamic Stiffness of Vibration Isolators
Uz, Canan; Özgen, Gökhan Osman; Ciğeroğlu, Ender (2014-01-01)
In this paper, design efforts to develop a custom test setup for measuring dynamic stiffness of vibration isolators are presented. The setup is designed to conduct dynamic stiffness measurements for various static preload values and over a certain (target) frequency range. Direct Method has been selected among the methods defined by standards found in the literature. In order to investigate the effect of basic design parameters of the test setup on its overall performance, an equivalent eight degree of free...
