Yatay su alma yapılarında hava sürükleyici vortekslerin oluşumu.

The goal of this study is to estimate the critical submergence depths of horizontal water intakes that have symmetrical and asymmetrical approach flow conditions by using empirical equations. Therefore a series of experiments were performed in a reservoir-pipe system dominated by gravity and controlled by a valve. On account of adjustable lateral walls, symmetrical and asymmetrical flow conditions were created at various Froude numbers. For a wide range of discharges and for three different pipe diameters, the critical depths of air-entraining vortices were observed. These observations were evaluated by dimensional analysis and dimensionless parameters were suggested. Finaly empirical equations were derived and the results were compared with similar studies in the literature.M.S. - Master of Scienc

Determination of critical submergence depth at horizontal intakes under asymmetric flow conditions

The purpose of the present study is to investigate the hydraulic conditions of air-entraining vortices under asymmetrical flow conditions and derive a general expression to determine the critical submergence depth required for the formation of these vortices at horizontal intake pipes. A series of experiments were conducted in a model composed of a concrete reservoir and intake pipe which was mounted horizontally to the reservoir. Three pipes of different diameters were tested with adjustable plexiglass side walls to investigate the effect of side-wall clearances on the critical submergence depth. Based on the experimental results obtained from a wide range of side-wall clearances and discharges, empirical equations for the critical submergence depth were derived and compared with Gordon's (1970) relationship
