Analysis and Modeling of Combined Discharge through Box Culverts and over Contracted Broad-crested Weirs
An experimental investigation is conducted on simultaneous flow through culvert and over broad-crested weir. The flow at the culvert outlet is considered as submerged flow. Both the culvert and the broad-crested weir (BCW) widths are smaller than the channel width. The characteristics of the simultaneous flow through both structures and the effects of flow and geometrical parameters of the stru...
متن کاملHydraulic and Environmental Aspects of Long Crested Weirs
Long crested weirs are gaining popularity amongst the hydraulic engineers owing to obvious hydraulic advantage of flow magnification. These weirs can pass much higher floods from the available width of a natural water course. Such weirs may also be introduced in water treatment plants for mixing of chemicals. This paper discusses the advantages of long crested weirs, such as duckbill and labyri...
متن کاملEvaluating the performance of ANSYS-CFX software in simulation the velocity and pressure distributions over circular crested weirs
ANSYS-CFX is an effective and multipurpose software which can be used for simulation the computational fluid dynamics (CFD) solutions at all levels of complexity. This software can be used for numerical solution of two and three dimensional flows, compressible and incompressible flows, viscous and non-viscous flows, laminar and turbulent flows, Newtonian and non-Newtonian flows, porous media, s...

متن کاملCFD SIMULATION OF FLOW OVER CONTRACTED COMPOUND ARCHED RECTANGULAR SHARP CRESTED WEIRS
Measurement of discharge in open channels is one of the main concerns in hydraulic engineering. The structures used for this aim should be accurate, economical and easy to use. Weirs are among the oldest and most convenient hydraulic structures that have been used in both laboratory and field for flow measurement in open channels. Due to limitations of simple sharp crested weirs, recently compo...
