Screens may be utilized efficiently for dissipating energy of water. In this study, water flowing beneath a gate is used to simulate the flow downstream of a hydraulic structure and screens are used as an alternative tool for energy dissipation. Investigations are done conducting a series of experiments. The porosity, thickness, and the location of the screens are the major parameters together with the Froude number of the upstream flow. The experiments covered a range of Froude numbers between 5 and 18, porosities between 20% and 60%, and location of the screen up to 100 times of the undisturbed upstream flow depth. The thicknesses of the screens used are in the order of the undisturbed upstream flow depth. The results show the importance of each parameter on the energy dissipating performance of the screens and the system. It is observed that screens dissipate more energy than a jump within the Froude number range covered in the present study.

Experimental investigation of energy dissipation through screens Çakır, Pınar; Bozkuş, Zafer; Ger, Metin; Department of Civil Engineering (2003) Screens may be utilized efficiently for dissipating the energy of water. In this study, water flowing beneath a gate is used to simulate the flow downstream of a hydraulic structure and screens are used as an alternative mean for energy dissipation. Investigations are done conducting a series of experiments. The porosity, thickness, and the location of the screens are the major parameters together with the Froude number of the upstream flow. The scope of this thesis covers the situation where there is a pse...
Tailwater effect on the energy dissipation through screens Bozkuş, Zafer (null; 2008-09-17) Previous studies have shown that screens may be utilized efficiently for dissipating the energy of water. For the present study, a series of experiments are executed to investigate the tailwater and multiple screen effects on the energy dissipation through screens. Water flowing beneath a sliding gate is used to simulate the flow downstream of a hydraulic structure. In the present study, one double screen and two double screen arrangements with porosity of 40% and inclination angle of 90 degree is used. A t...
Energy dissipation by vertically placed screens Bozkuş, Zafer; GER, A. Metin (Canadian Science Publishing, 2007-04-01) Screens can be utilized efficiently for dissipating energy of water. In this study, water flowing beneath a gate is used to simulate the flow downstream of a small hydraulic structure, and vertically placed screens are used as an alternative tool for energy dissipation. Investigations are conducted using a series of experiments. The porosity, thickness, and location of the screens are the major parameters together with the Froude number of the upstream flow. The experiments cover a range of supercritical Fr...
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...
