Abstract
Turbulent flow in a narrow open channel is investigated using the large-eddy simulation (LES) technique in which the surface is allowed to freely deform. A relatively large Reynolds number of 90,400 (defined as 4RUmean/) is used in the simulation and it is shown that good resolution is required in order to reproduce the effects of the turbulence-driven secondary currents. The simulated results are in good agreement with experimental measurements and previous calculations.Keywords
