CFD for flow in fractured rocks

January 22, 2001, 18:23

I am interested in CFD to model flow in fractured rocks. Traditionally, Darcy's law has been used to model flow in porous media: however, it is said that there are limitations on Darcy's law to be applied to flow in rock fractures. It would be very appreciated, if anyone who has practical experiences in this issue could tell me what these limitations are.

Thanks

The flow in the fructure may not be laminar any more. It is most probibly turbulence, thefore the Darcy's may fail.

Dear Al-Shaaln,

Could you give me refereces on this issue?
