Numerical investigation of operation levels in a surge tank of a small hydropower plant
Çalamak, Melih; Bozkuş, Zafer (2012-10-19)
It is important that engineers in charge of operating a small hydro power plant (SHPP) have accurate information regarding safe operation levels of a surge tank installed as a surge protection device in the energy producing facility. Typically, minimum and maximum operation levels of water surface in a surge tank are determined by the engineers in practice, using some available simplified equations. As will be demonstrated in the present study, the results of those simplified equations may differ greatly fr...
Experimental and numarical investigation of carbon dioxide sequestration in deep saline aquifers
İzgeç, Ömer; Demiral, Birol; Department of Petroleum and Natural Gas Engineering (2005)
Started as an EOR technique to produce oil, injection of carbon dioxide which is essentially a greenhouse gas is becoming more and more important. Although there are a number of mathematical modeling studies, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to characterize relevant chemical reactions associated with injection and storage...

Ozalay, M; Akpinar, S; Karaeminogullari, O; Balcik, C; Tasci, A; Tandogan, RN; Gecit, R (Elsevier BV, 2005-08-01)
Purpose: The aim of this study was to compare the biomechanical properties of 4 different biceps tenodesis techniques. Type of Study: Biomechanical experiment. Methods: Four groups of fresh sheep shoulders (28 total) with similar shape characteristics were used. Biceps tenodesis was performed using the following techniques: group I (n = 7), tunnel technique; group 2 (n = 7), interference screw technique; group 3 (n = 7), anchor technique; and group 4 (n = 7), keyhole technique. Each construct was loaded to ...
Optimum placement of microphone array for sound capture using genetic algoritms
Birinci, Isil Yazgan; Leblebicioğlu, Mehmet Kemal (2006-01-01)
This paper presents a new method based on genetic algorithm for the optimum placement of microphone arrays for high-quality sound pickup. Microphone arrays are being used for the purposes of direction-of-arrival estimation and tracking of sound sources [1][2] as well as high quality sound capture by focusing on a source [3]. The placement of microphones has direct effect on the sound quality acquired [4][5]. The method proposed in this paper uses a metric function that takes this effect into account and op...
Boş Bir Boru Sisteminde Değişken Akımlı Bir Su Kütlesinin Paketinin Hidrodinamiği
Bozkuş, Zafer (1995-01-01)
Liquid slugs (water pockets) are propelled into an empty pipe under various driving pressures; the pipe's extension ends at an elbow whereon the slugs impact and disintegrate. Dynamic pressures recorded at various locations along the system indicate the complex and somewhat random structure of the transient. High-speed movies of the evolving slug just prior to impact show that significant air entrainment and breakup of the slug occurs. A simplified analytical model is developed to predict the slug dynamics;...
