Dear All,
In Nays2DH, it provides 3 different turbulent models. Constant eddy viscosity, Zero equation and K-epsilon model. What are the advantages/disadvantages of those models? What is the best model to investigate secondary currents generated by a vegetation patch near an embankment?
Thanks!
Romitha.

Hello,
It is explained in manual P9, but it depends on the grid spacing etc.
Generally, I think the K-E model has higher accuracy.
Please compare yourself for details.
Regards,
Reynolds-Averaged Navier-Stokes (RANS) models are often used for turbulent flows in which the turbulence scales are larger than the grid size. These models solve for the time-averaged quantities of velocity and pressure, and often employ a turbulence model to model the effects of the unresolved turbulence scales.
