EFFECTS OF RELATIVE DEPTH BETWEEN MAIN CHANNEL AND FLOOD-PLAIN ON TURBULENT STRUCTURE IN COMPOUND OPEN-CHANNEL FLOWS

Assessment of Turbulent Models in Computation of Strongly Curved Open Channel Flows

Several rigorous turbulent models have been developed in the past years and it can be seen that more research is needed to reach a better understanding of their generality and precision by verifying their applications for distinct hydraulic phenomena; under certain assumptions. This survey evaluates the performance of Standard k-ε, Realizable k-ε, RNG k-ε, k-ω and RSM models in predicting flow ...

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 ...

Turbulent flows in straight compound open-channel with a transverse embankment on the floodplain

24 The present study deals with turbulent flows in an asymmetrical compound channel with an 25 embankment set on the floodplain, perpendicularly to the longitudinal direction. The main purpose of 26 this study was to assess how a rapidly varied flow affects interaction between the floodplain flow and 27 the main channel flow. In addition to rapid changes in the water level and velocity across t...
