Numerical simulation of flow over a rough bed [PDF]
, 2004 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.

On modeling chronic detachment of periphyton in artificial rough, open channel flow [PDF]
, 2012 Periphyton communities, which are native to river beds, serve as a functional indicator of river health but remain one of the least-studied communities despite the significant increase in the examination of aquatic microbial communities in recent years ...

Turbulence structure of non-uniform rough open channel flow
E3S Web of Conferences, 2018 This paper focuses on the turbulence structure in a non-uniform, gradually varied, sub-critical open channel flow (OCF) on a rough bed. The flow field is analysed under accelerating, near-uniform and decelerating conditions.

Exploring impacts of inlet condition on flow structure in a Compound open-channel using PIV [PDF]
مهندسی مکانیک شریف, 2021 A compound open channel is composed of the main channel and flood plain. In experiments with compound open channel conducted to ensure that the flow is uniform and fully developed, it is necessary to study the distribution of discharge in the main ...

Extended theory of hydraulic hysteresis in open channel flow [PDF]
, 2017 The occurrence of hysteresis in a supercritical, open-channel flow approaching an obstacle has been recognized and investigated both experimentally and theoretically over the last few decades. However, the available theory and experimental investigations

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 ...
