Numerical Study Scour Pattern on Channel Bend Using Flow-3D Software
In nature, a direct route to the river is uncommon. Most rivers have channels that bend wherea complex scour pattern dominates. We have intended to study the behavior patterns necessary to scour a river known as the dominant bends. Numerical models are powerful instruments for the prediction of such areas and can provide a good understanding of these areas. In the present study we have used a t...
متن کاملDesign of curved waveguides: the matched bend.
A new criterion for the optimum design of curved dielectric waveguides is proposed. The bends designed according to this model are named matched bends. In the matched bend, the suitable choice of both bending radius and bending angle reduces the total losses of the bend and avoids the leaky-mode excitation at the end of the bend. For a given angle, a discrete number of bending radii that satisf...
متن کاملThe effect of the geometry of the scour around bridge abutments in the river bend
Every year a large number of bridges flooding in the river just when they most need them there destroy all born. Carried out. In this study, the four fulcrum forms a semi-circular, trapezoidal, rectangular edges rounded rectangle 90 degrees at 70 degrees in Sagittarius with four different discharges depth of constant scouring around the abutment in pure water were examined. For material of flum...

15 صفحه اولinvestigation on time variation of scour around t shape spur dike in a 90 degree bend
spur dike is an important element for protection of river banks. spur dike causes variations in flow field, sediment transport and bed topography. the mechanism of flow and sediment transport in a channel bend is very complex, especially when a spur dike is constructed in a bend. in this paper the time variations of dimension of the scour hole and the bed’s topography were considered around a t...
