Open channels can range from small irrigation furrows to huge irrigation canals that are hundreds of kilometers long and supply billions of cubic meters per year for irrigation, industry, and domestic purposes. Agricultural canal categories include the irrigation district main, secondary and tertiary canals, laterals, on-farm irrigation ditches, and ...

This study presents an analytical attempt to explore the two-dimensional concentration distribution in an open channel flow. Mei’s homogenization technique is used to find the transverse concentration distribution up to third order approximations.

In an open channel flow, only part of the current is at contact with walls and a free surface is present, usually at atmospheric pressure. In most cases, the curvature of the trajectories is negligible and a hydrostatic pressure distribution is achieved.

Settling velocity of fine heavy particles in turbulent open channel flow
The Physics of Fluids, 2018The settling velocity of heavy particles with sub-millimetre diameters falling in a turbulent open channel flow is investigated using a two-camera imaging technique of simultaneous particle image velocimetry and particle tracking velocimetry. Flow images

Open channels are conduits in which a fluid has a free surface or its boundary is exposed essentially to the atmosphere, and open-channel flows are referred to as liquid flows with free surfaces. An open channel is not completely filled by a liquid in general, which introduces the concept of wetted perimeter.

Recirculating flow-induced anomalous transport in meandering open-channel flows
, 2020Channel meanders in rivers induce complex three-dimensional (3D) flow characteristics such as secondary flows and flow recirculation. Helical secondary flows promote transverse dispersion, and flow recirculation zones trap tracers.

Self-aeration development and fully cross-sectional air diffusion in high-speed open channel flows
Journal of Hydraulic Research, 2022Self-aeration in open channel flows occurs owing to free surface air entrainment. Self-aeration development and fully cross-sectional distribution of air concentration are not thoroughly understood.

Flow in open channels has been nature’s way of conveying water on the surface of the earth since the beginning of time. The following physical properties of fluids influence fluid motion, channel geometry, and help explain sediment transport. These are: mass; density; weight; specific weight; viscosity; shear; temperature; and elasticity and surface ...

Central schemes for open‐channel flow
International Journal for Numerical Methods in Fluids, 2003AbstractThe resolution of the Saint‐Venant equations for modelling shock phenomena in open‐channel flow by using the second‐order central schemes of Nessyahu and Tadmor (NT) and Kurganov and Tadmor (KT) is presented. The performances of the two schemes that we have extended to the non‐homogeneous case and that of the classical first‐order Lax ...

Parallel simulation of flows in open channels
Future Generation Computer Systems, 2002Summary: In this project, we apply our advanced free-surface flow solver to simulate flow in open channels at supercritical conditions. The finite element method is used to discretize the governing equations over fixed meshes. The finite element formulations have been implemented in parallel using message passing interface libraries.
