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 tailwater gate structure is used to adjust the tailwater depth. The major parameters for the present study are upstream flow depth, tailwater gate height, location of the screen together with the supercritical upstream flow Froude number for a range covering from 5.0 to 22.5. The gate opening simulating a hydraulic structure is adjusted at heights of 2 cm and 3 cm during the study. The results of the experiments show that the tailwater depth has no significant additional contribution on the energy dissipation, whereas multiple screen arrangement dissipates more energy as compared to one double screen arrangement.

Energy Dissipation Through Screens Bozkuş, Zafer; Ger, Ahmet Metin; Özeren, Yavuz (null; 2004-07-01) 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, po...

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...
