The aim of this experimental study is to investigate the effects of hydraulic parameters on the formation of air-entraining vortices at horizontal intake structures without approach flow induced circulation. Six intake pipes of different diameters were tested in the study. The intake pipe to be tested was horizontally mounted to the front side of a large reservoir and then for a wide range of discharges experiments were conducted and critical submergences were detected with adjustable approach channel sidewalls. Empirical equations were derived for the dimensionless critical submergence as a function of the relevant dimensionless parameters. Available data is also checked for the possible scale effect. Then, these obtained equations were compared with the similar ones in the literature which showed a quite good agreement.

Determination of critical submergence depth at horizontal intakes under asymmetric flow conditions
Göğüş, Mustafa; Köken, Mete; Haspolat, Emre (2015-07-03)
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 sid...
Effect of approach channel shape on theformation of vortices at single-horizontal intakes
Sönmez, Can Metin; Göğüş, Mustafa; Department of Civil Engineering (2019)
In an experimental setup of a water intake structure composed of a reservoir-pipe system, the formation of air-entraining vortices under symmetric flow conditions were investigated for different approach channel shapes. In the first set of the experiments the approach channel walls were kept parallel to each other and be perpendicular to the head-wall of the intake structure. In the following sets of the experiments these walls were located at different angles to the head-wall. A series of experiments were ...
Formation of air-entraining vortices at horizontal water intakes /
Zaloğlu, Cihan; Göğüş, Mustafa; Department of Civil Engineering (2014)
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, ...
Investigation of critical submergence at single and multiple- horizontal intake structures having air- entraining vortices
Gökmener, Serkan; Göğüş, Mustafa; Department of Civil Engineering (2015)
In this experimental study the variation of the critical submergence of air- entraining vortices with important flow and geometrical parameters were investigated at single and multiple- horizontal intake structures. In the scope of this study, three identical pipes of diameter Di=0.265 m were tested at a wide range of discharge with varying side wall clearances under symmetrical and asymmetrical approach flow conditions. Using dimensional analysis dimensionless equation was developed for critical submergenc...
Determination of critical submergence depth at horizontal intakes
Haspolat, Emre; Göğüş, Mustafa; Köken, Mete; Department of Civil Engineering (2015)
The purpose of the study is to investigate the formation of air entraining vortices under both symmetrical and asymmetrical approach flow conditions in an experimental setup of a horizontal water intake structure composed of a reservoir-pipe system. To determine at which critical submergence the air entraining vortices forming; a series of experiments were conducted in the experimental setup with horizontal pipes of four different diameters. Approach channel side walls of the intake structure model are adju...
