Numerical analysis of on the effects of Hydrokinetic turbine presence in flow structure of a compound open-channel
In the recent years, due to the hydropower plants environmental problems, hydrokinetic turbine usages has been increased. Using such turbines in rivers modify natural flow-field. In previous studies, impacts of turbine on the flow-field just only in rectangular open-channel is studied. In this work, the effects of hydrokinetic turbine in a straight compound channel has been numerically studied ...
متن کاملUnsteady 1D flow model of compound channel with vegetated floodplains
In areas that are occasionally inundated by floods, it is essential to know the quantity and density of vegetation that can be allowed while avoiding flooding beyond the intended floodplains. An unsteady flow model was developed for a channel with vegetated floodplains, to take into account the retention effects of the vegetated areas on flood wave conveyance. A one-dimensional (1D) unsteady fl...

3 The purpose of this study was to quantify how vegetation influences the flow and sediment processes 4 relevant for the design and management of environmental compound channels. Therefore, we conducted a 5 two-year field investigation in a cohesive two-stage channel, focusing on the flow resistance and net 6 deposition in five sub-reaches with different floodplain vegetation conditions. In the...
متن کاملVortex Identification in the Wall Region of Turbulent Channel Flow
Four widely-used techniques for vortex detection in turbulent flows are investigated and compared. The flow of a viscous incompressible fluid in a plane channel is simulated numerically by means of a parallel computational code based on a mixed spectral-finite difference algorithm for the numerical integration of the Navier-Stokes equations. The DNS approach (Direct Numerical Simulation) is fol...
