turbulence, RANS model
turbulence, RANS model
(OP)
Hi everyoone,
I'm using a RANS model, with k-epsilon turbulence model (IH2VOF).
One of the options in the model setup is to 'activate turbulence' and then specify 3 parameters (turbulence seed parameter, eddy viscosity and a parameter for boundary layer turbulence).
My question is if I choose not to include turbulence what is happening to the equations? they became NS?
Many thanks

RE: turbulence, RANS model
As far as the equations becoming Navier-Stokes: if you have no turbulence closure calculating an eddy viscosity, and no prescribed eddy viscosity, then the equations would be Navier-Stokes (instead of Reynolds-averaged Navier-Stokes, which includes turbulence via an eddy viscosity).
