The demand on high efficiency pumps leads the manufacturers to develop new design and manufacturing techniques for rotodynamic pumps. Computational Fluid Dynamics (CFD) software are started to be used during the design periods for this reason in order to validate the designs before the pumps are produced. However the integration process of CFD software into the design procedure should be made carefully in order to improve the designs. In this thesis, the CFD software is aimed to be integrated into the pump design procedure. In this frame, a vertical turbine type mixed flow pump is aimed to be designed and design improvements are intended to be made by applying numerical experimentations on the pump. The pump that is designed in this study can deliver 115 l/s flow rate against the head of 16 mWC in 2900 rpm. The effects of various parameters in the design are investigated by the help of CFD software during the design and best performance characteristics of the pump are aimed to be reached. The pump that is designed in this study is manufactured and tested in Layne Bowler Pumps Company Inc. The design point of the pump is reached within the tolerance limits given in the related standard. In addition, the results of actual test and numerical experimentation are compared and found to be in agreement with each other. The integration of CFD code to the design procedure is found quite useful by means of shortening design periods, lowering manufacturing and testing costs. In deed the effects of the design parameters are understood better by applying numerical experimentations to the designed pump.

Assessment of sheet metal forming processes by numerical experiments
Önder, İ. Erkan; Tekkaya, A. Erman; Department of Mechanical Engineering (2005)
Sheet metal forming technologies are challenged especially by the improvements in the automotive industry in the last decades. To fulfill the customer expectations, safety requirements and market competitions, new production technologies have been implemented. This study focuses on the assessment of conventional and new sheet metal forming technologies by performing a systematic analysis. A geometry spectrum consisting of six different circular, elliptic, quad cross-sections are selected for the assessment ...
Analysis and design for aluminum forging process
Öztürk, Hüseyin; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2008)
Aluminum forging products has been increasingly used in automotive and aerospace industry due to their lightness and strength. In this study, aluminum forging processes of a particular industrial part for the two different alloys (Al 7075 and Al 6061) have been analyzed. The forging part, forging process and the required dies have been designed according to the aluminum forging design parameters. The proposed process has been simulated by using the Finite Volume Method. In the simulations, analysis of the p...
Assesment of roll-formed products including the cold forming effects
Güner, Alper; Kılıç, S. Engin; Department of Mechanical Engineering (2007)
Roll-forming is an efficient sheet forming process that is used in manufacturing long parts with constant cross-section. The theoretical, experimental and numerical analyses of the process are limited since the sheet takes a complex 3D shape during the process. In this study proper finite element method models to simulate the roll-forming process are examined both numerically and experimentally. In addition, the applicability of 2D plane strain models to the simulation of the process is investigated. To rev...
Conceptual design and analysis of an industrial type vacuum sweeper
Aygün, Buket; Albayrak, Kahraman; Department of Mechanical Engineering (2009)
In this thesis, design and development and manufacturing processes of an industrial type vacuum sweeper is presented. Thesis is financially supported by Ministry of Industry and Trade-Turkey and Müsan A.Ş. (Makina Üretim Sanayi ve Ticaret A.Ş.) under SAN-TEZ project number 00028.STZ.2007-1. It is aimed to make innovative design changes and developments on the Müsan VSM 060 type vacuum sweeper. To achieve this aim, alternative configuration designs are prepared by using commercial 3D modeling program, Catia™...
Mechanical characterization and modelling of porous polymeric materials manufactured by selective laser sintering
Tekin, Cevdet Murat; Dağ, Serkan; Department of Mechanical Engineering (2009)
Rapid prototyping methods embrace a family of manufacturing methods that are developed to speed up the prototyping stage of product design. The sole needed input for production being the solid model of the part, mold/tool-free production characteristics and the geometric part complexity that can be achieved due to layer-by-layer production have extended the applicability/research areas of these methods beyond prototyping. Local pore formation in part that occurs as a result of the discrete manufacturing nat...
