Effect Of Flow Resistance In Open Rectangular Channel [PDF]

MATEC Web of Conferences, 2017
The determination of flow resistance for open channels remains a challenge in practices. In this research, an experimental study was carried out to investigate the hydraulic roughness characteristics in an open channel.

Level Set method-based two-dimensional numerical model for simulation of nonuniform open-channel flow. [PDF]

PLoS ONE, 2019
The capture precision of the free surface of an open-channel with a water-air interface directly affects the calculation precision of flow field characteristics and general characteristics of the flow.

Free surface bubbly flow in an open capillary channel [PDF]

npj Microgravity
This study investigates bubbly flow in a rectangular open channel under microgravity. A homogeneous flow model is used to compute frictional pressure loss and then establish a correlation between the drag coefficient and mass quality, leading to a one ...

Self-similarity of spanwise rotational motions’ population trends in decelerating open-channel flow

Theoretical and Applied Mechanics Letters, 2022
Decelerating open-channel flow is a type of flow that gradually moves forward with decreasing velocity and increasing water depth. Although all flow parameters change along the streamwise direction, previous studies have revealed that these parameters ...

Shear Flows of Rapidly Flowing Granular Materials [PDF]

, 1987
Shear flows of granular materials are studied in an open channel. The wall shear is calculated from an open channel momentum equation which includes the density variations in the flow.

Modal decomposition of linearized open channel flow

Networks and Heterogeneous Media, 2009
Open channel flow is traditionally modeled as an hyperbolic system of conservation laws,which is an infinite dimensional system with complex dynamics. We consider in this paperan open channel represented by the Saint-Venant equations linearized around a ...

TRANSIENT FLOW IN A RECTANGULAR OPEN CHANNEL

Journal of Engineering, 2005
In this paper, the transient flow in a rectangular open channel has been studied for different conditions. The velocity and depth of water have been calculated at different sections in the channel. A computer program (Channel) was developed to solve the

Settling of Mesoplastics in an Open-Channel Flow

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.
