Abstract

Separation zone and shear face generate most turbulence in confluence junctions. Flume experiment studies show the variation of a separation zone from the water surface to the bottom and impacts of the two circulation cells (secondary flow) on the sediment transportation in a confluence zone. The turbulence generated by the shear face is anisotropic, so it needs to be cautious to choose appropriate turbulence models in the simulation of confluence flow. This article utilizes the standard k - ε, RNG k - ε, and RSM turbulence models to simulate the secondary flow and separation zone in the confluence junction, and a quantificational comparison with the experiment data is provided. © 2011 Copyright Taylor and Francis Group, LLC.
