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

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.
