How to include a crossmix in fluent
 

Hi all

Can anyone please provide me an idea how to include a cross mix(a device which is used to mix the flow). (For example, a crossmix has a cylindrical shape and a lot of equisized holes in it). I think i can use porous media option in FLUENT, but I'm not sure how to implement the properties of the particular Crossmix in the FLUENT case. Please let me know how to do this.

Thanks in advance
