Turbulent flow through porous medium?
 
When does a flow through a porous medium become turbulent?Can such problems be solved with Fluent? Thanks. Shankar.

i think Fluent can. for some my colleagues are working at this.

Re: Turbulent flow through porous medium?
 
FLUENT models porous media flow as a fluid region with an extra momentum sink term. As such, it CAN model turbulence in a porous medium but CANNOT account for any fluid-structure interactions that might promote or suppress turbulence. If you want to include that, you would have to write some sort of UDF.

Re: Turbulent flow through porous medium?
 
Thanks to both of you, so when is a flow considered turbulent in a porous medium? Shanjar.
