This experimental study analyzes submerged hydraulic jumps generated in a 1.05-m wide stilling basin that receives overflow rectangular impinging jets, with the vertical distance between sharp-crested weir and bottom of plunge pool being 2.20 m. Five downstream non-developed nappe jets were analyzed, falling distances to break-up length ratios 0.76 0.78. The impingement velocity range was from ...

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...

Abstract Present study highlights the behavior of weir crest head and width parameter on discharge coefficient a compound broad crested (CBC) weir. Computational fluid dynamics model (CFD) is validated with laboratory experimental investigations. In analysis through weirs, upstream over (h) crucial, where result mainly dependent upon length (L) in transverse direction to flow, water depth from ...

With the continuous operation of check dams, silting elevation whole dam gradually increases. When height is close to broad-crested weir, it will result in a large change hydraulic characteristics original flow pattern. For subsequent reinforcement work, necessary know how excessive sediment deposition affects overflow from weir into spillway. However, few studies about discharge coefficients a...
