discharge coefficient in vertical intakes with additional plates
نویسندگان
چکیده
one of the causes of perturbation at vertical intakes is the happening of vortices with an air core. the vortices with an air core occur whenever the submergence of the intake is less than a critical value. anti-vortex devices and specially plates are used to avoid the negative effects of the air-core vortices. if plates are used, then the geometry of them should be studied experimentally. accordingly, a precise set of experiments have been carried out using rectangular plates with different dimensions. the results showed that using the vertical plates can increase the critical submergence for the same discharge rates to 51%.

متن کاملِِDischarge Coefficient in Oblique Side Weirs
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

abstract bottom intake is one of the most appropriate systems for diverting discharge in steep rivers. bottom intake with porous media is a new system of diverting discharge which can be replaced by bottom rack intakes. to investigate the hydraulic flow characteristics on diverted discharge of this intake, an experimental model was designed in which the inflow, diverted discharge and remained f...
متن کاملThe External Drag of Fuselage Side Intakes: Rectangular Intakes with Compression Surfaces Vertical
SUMMARY An experiment designed to measure the external drag of fuselage side intakes is described. The scope of the experiment and the techniques employed are discussed and an assessment is made of the accuracy of results. Measurements of the external drag of rectangular intakes installed on the sides of a fuselage are presented. Results at subsonic speeds show that drag at full flow is indepen...

متن کاملFilm condensation on non-isothermal vertical plates
An analytical study is presented of the condensation of a pure saturated vapour on a cooled channel plate, including the interaction between the cooling liquid, the condensate and the vapour. The governing equations of co-, counterand cross-current condensation are derived, set dimensionless and solved in closed form. The resulting implicit expressions are evaluated numerically by iteration. In...
