EXPERIMENTAL STUDY OF FLOW IN CURVED RECTANGULAR OPEN CHANNEL WITH SIDE CONCAVITY

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 ...

Shape Effects and Definition of Hydraulic Radius in Manning 's Equation in Open Channel Flow

In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...
