Turbulence Model for low Reynolds Number
 
Dear CFD people

My problem includes flow over cylinders in narrow channel at low Reynolds Number. Which turbulence model will be more suitable.

Dear Muhammad,

I would suggest a k-family turbulence model with low Re correction, like the Low Re formulation of k-e model.

Regards,

Ganesh

Re: Turbulence Model for low Reynolds Number
 
If two-equation model does your job (no adverse pressure gradients and boundary layer separation), then Mentors SST model should do fairly well.

If you want to compute with Second-moment closures, I suggest to adopt models which use omega equation near the wall and epsilon equation away from the wall. In CFX this model is named as Second-moment omega model.

hope this will help you.
