A hybrid RANS-LES model for combining flows in open-channel T-junctions

In the present study, a hybrid RANS-LES (Reynolds Averaged Navier-Stokes equation - Large Eddy Simulation) model is developed for the simulation of open-channel T-junction flows. The hybrid approach can save computational effort comparing to the LES approach. The comparison between the computational results and the detailed experimental data shows that this relatively new modeling approach is more accurate than the RANS approach in the prediction of the combining flows in T-junctions.
