flow through a porous medium
 
I am doing simulations which involve flows through ceramic filters. Do you know where I can find accurate values of their permeability to put them in the porous medium model?

Thanking you in advance Vangelis Skaperdas

Re: flow through a porous medium
 
hi vangelis,

we have some experience with cfd calculations for porous flows. first of all you should know if you want to make a mikroscopic model including the pores or (in most cases sufficient) a makroscopic (averaged) one modeling only the pressure jump by (volume)body forces. in this case you have to know - from experiment - the presure drop vs volume flow relationship. for some cases there are tabulated values and /or empical formulas. unfortunately i have it only in german.
