Friction factor for turbulent open channel flow covered by vegetation. [PDF]

Sci Rep, 2019
The need for operational models describing the friction factor f in streams remains undisputed given its utility across a plethora of hydrological and hydraulic applications concerned with shallow inertial flows.

Settling of Mesoplastics in an Open-Channel Flow [PDF]

Energies, 2022
Pollution of water by plastic contaminants has received increasing attention, owing to its negative effects on ecosystems. Small plastic particles propagate in water and can travel long distances from the source of pollution.

Flow Patterns in an Open Channel Confluence with Increasingly Dominant Tributary Inflow

Water (Switzerland), 2015
Despite the ratio of incoming discharges being recognized as a key parameter in open-channel confluence hydrodynamics, little is known about the flow patterns when the tributary provides more than 90% of the total discharge.

Influence of submerged flexible vegetation on turbulence in an open-channel flow

Journal of Fluid Mechanics, 2022
Abstract In this study, we present a three-dimensional numerical model for the interaction of flow with submerged flexible vegetation, based on a large-eddy simulation and the immersed boundary method.

Secondary currents and very-large-scale motions in open-channel flow over streamwise ridges

Journal of Fluid Mechanics, 2020
It is widely acknowledged that streamwise ridges on the bed of open-channel flows generate secondary currents (SCs). A recent discovery of meandering long streamwise counter-rotating vortices in open-channel flows, known as very-large-scale motions ...

SPH modelling of turbulent open channel flow over and within natural gravel beds with rough interfacial boundaries

Advances in Water Resources, 2020
Smoothed Particle Hydrodynamics (SPH) is brought to a level that can be applied to simulate turbulent open channel flows over and within natural porous gravel beds.

Impact of dynamic factors on the exchange flow between two neighboring bays with contrasting topography during summer: A numerical study

Frontiers in Marine Science, 2023
A high-resolution, three-dimensional numerical ocean model was employed to understand the exchange flow through Noryang Channel, which connects Gwangyang Bay and Jinju Bay.
