Unsteady Flow Patterns between Two Egg-Carton Corrugated Plates
Engineering Transactions, 2021 Unsteady analyses of the flow between two egg-carton corrugated plates were performed. Geometry effects on the flow were as follows: “closed recirculations” shrank downstream the channel and became “open recirculations”.

Numerical simulation of flow over a rough bed [PDF]
, 2007 This paper presents results of a direct numerical simulation (DNS) of turbulent flow over the rough bed of an open channel. We consider a hexagonal arrangement of spheres on the channel bed.

Turbulence structure in open channel flow with partially covered artificial emergent vegetation
Journal of Hydrology, 2019 An innovative approach was recently proposed to increase water depth and improve navigation in rivers by increasing overall roughness through an adaptive placement of artificial vegetation.

Flow Resistance in Open Channel Due to Vegetation at Reach Scale: A Review
, 2021 Vegetation on the banks and flooding areas of watercourses significantly affects energy losses. To take the latter into account, computational models make use of resistance coefficients based on the evaluation of bed and walls roughness besides the ...

Effect of near‐bed turbulence on chronic detachment of epilithic biofilm: Experimental and modeling approaches. [PDF]
, 2010 The biomass dynamics of epilithic biofilm, a collective term for a complex microorganism community that grows on gravel bed rivers, was investigated by coupling experimental and numerical approaches focusing on epilithic biofilm‐flow interactions.

Modeling and Analysis of Fluid Flow through A Non-Prismatic Open Channel with Application to Drilling [PDF]
Modeling, Identification and Control, 2018 This paper presents the development and validation of a simplified dynamic model of a Venturi channel. The existing dynamic models on open channels are based on the open channel flow principles, which are the shallow water equations.

Very-large-scale motions in rough-bed open-channel flow
Journal of Fluid Mechanics, 2017 Long-duration particle image velocimetry measurements in rough-bed open-channel flows (OCFs) reveal that the pre-multiplied spectra of the streamwise velocity have a bimodal distribution due to the presence of large- and very-large-scale motions (LSMs ...

Turbulent Micropolar Open-Channel Flow
FluidsThe present paper focuses on the investigation of the turbulent characteristics of an open-channel flow by employing the micropolar model. The underlying model has already been proven to correctly describe the secondary phase of turbulent wall-bounded ...
