The performance of outlets under constant head is investigated in this study. Behavior of single outlet is analyzed; subsequently effect of multiple outlets on a single outlet is examined. Parameters taken into account are constant head of water, orifice shape, orifice length, number of open outlets and discharge. The outlet type, which is examined, can be classified as a short tube orifice. Two different orifice diameters and tube lengths are used. Outlets had the diameter, 6.00 and 10.35mm. The ratio of orifice length to diameter (l/d) was 5 and 8. Number of outlets is 5, which are opened in several combinations. A dimensional analysis shows that discharge coefficient, Cd is a function of diameter-length ratio and the Reynolds Number. In this study, high Reynolds Number (2300

Comparative study on sediment transport equations for delta formations in reservoirs Pulcuoğlu, Başar; Tiğrek, Şahnaz; Department of Civil Engineering (2009) In this study, a qualitative and comparative investigation on sediment transport equations used in prediction of rserevoir sedimentation is presented. 32 sediment transport equations, which are selected by literature review on sand and gravel size ranges, grouped according to the median particle sizes on which their derivation based. In order to compare these equations computer program DELTA, which is a one dimensional simulation program developed by Graf and Altınakar (1998) for the prediction of delta for...
Experimental investigation of energy dissipation through inclined screens Balkış, Görkem; Bozkuş, Zafer; Department of Civil Engineering (2004) The main goal of the present study is to investigate the energy dissipation through inclined screens. Recent studies have shown that screens arranged vertically may dissipate more energy than a hydraulic jump does below small hydraulic structures. In the present study a series of laboratory experiments were performed in order to determine the effect of inclination of the screen on the energy dissipated by the screen. The porosity of the screen used in the experiments is 40%. Inclination angle, thickness of ...
Experimental investigation of energy dissipation through triangular screens Güngör, Endam; Bozkuş, Zafer; Department of Civil Engineering (2005) For the present study, a series of experimental works are executed to dissipate energy through triangular screens. Recent studies have shown that the implementation of the screen for energy dissipation is an effective way to extract out the excessive energy of water downstream of small hydraulic structures located in rivers of relatively negligible sediment content. In the present study, double screen arrangement with a porosity of 40% is used. The inclination angle of the screens is opted as 60 degree. The...
Energy dissipation by triangular screens Bozkuş, Zafer; Ger, Ahmet Metin (null; 2006-10-13) The main drive for the present study is to investigate experimentally the energy dissipation through triangular screens. Recent experimental studies have shown that screens placed in vertical and inclined configurations below small hydraulic structures may dissipate more energy than a hydraulic jump formed in conventional stilling basins. In the present study a series of laboratory experiments were performed in order to determine the effect of triangular screens on the energy dissipation. The location of th...
Scale effects on the formation of vortices at intake structures Gürbüzdal, Ferhat Aral; Göğüş, Mustafa; Department of Civil Engineering (2009) In the present study, possible scale effects on the formation of air-entraining vortices at horizontal intakes are studied experimentally. Basic dimensionless parameters that govern the onset of vortices at a horizontal intake in a model and a prototype are stated by dimensional analysis. Series of experiments are conducted on four intake pipes of different diameters located in a large reservoir. The relationship of critical submergence ratio with other dimensionless parameters is considered for a given Fro...
