Abstract:
In this study, the full Launder, Reece and Rodi pressure-strain model and nonlinear boundary damping functions were incorporated in OpenFOAM® to simulate the turbulence-driven secondary currents in supercritical narrow channel flows such as in sediment bypass tunnels (SBTs). Five simulations were performed under uniform flow conditions covering Froude numbers from 1.69 – 2.56 and aspect ratios (channel width to flow depth) ar from 0.9 – 1.91 to investigate the formation of secondary currents and...     »
