Modelling Relative Permeability in Porous Mdeia

      Greetings,


      I am new user of ANSYS Fluent ,and I am trying to model Oil contamination in ground soil with variable water saturation using the late ANSYS Fluent 18.2 update in modelling the Multiphase flow in  porous media using mixture model .


       


      And I am using multiphase mixture model using three Eulerian phases to account for water, oil and Air.


      So the question is, I cant activate/find the Corey Model option after checking the porous zone condition in the cell zone condition dialogue box ,which I found following the Help section "6.2.3.7.16. Specifying the Relative Permeability"  and still I can't find the same option after activating the porous media option.


      Any help would be appreciated.

      Hello Naggar,


      I am not sure if you have figured out where to activate 'Corey Model'. Here are some screenshots.



      • Select 'Eulerian model' in Multiphase. Enter the total number of phases.

      • Go to 'Cell Zone conditions'. Select the Zone you want to activate 'Porous zone' on. Ensure that the phase reads 'mixture'. 

      • Click on 'Edit'. Enable 'Porous zone' and you should be able to activate 'Corey Model' from the porous zone tab.


      Hope this helps.


      Best Regards,

      Thanks Karthik


      I have already found what I was preventing me from activation Corey model option,  as I was selecting the mixture model instead of Eulerian model which would resolve this issue.

      Hi Naggar,


      Glad to know! Good luck with your modeling!
