mass transfer

Good day everyone, how can I model mass transfer over a fluid-fluid-phase-border with Fidap 8.6, taking the distribution-coefficient into consideration? Thanks, best regards Ludwig

I just want to calculate the concentration X and Z of a species in two liquid phases with a boundary, as it is shown here:

/\ location__________________________________________ ____________________ ||________________________________________________ ______________________ ||ZZZZZZZ_________________________________________ ______________________ ||_______ZZZZ_____________________________________ ______________________ ||___________ZZZ__________________________________ ______________________ ||______________Z_________________________________ ______________________ ||===============Z_o==============X_o============= ======phase boundary ||____________________________________X___________ ______________________ ||_____________________________________XX_________ ______________________ ||_______________________________________XXXX_____ ______________________ ||___________________________________________XXXXX XXX___________________ ||________________________________________________ ___XXXXXXXXXXXXXXXXX

0 ===========> concentration of species

with:

X: concentration of species in phase 1

X_o: concentration of species in phase 1 at the boundary

Z: concentration of species in phase 2

Z_o: concentration of species in phase 2 at the boundary

with the distribution coefficient n = X_o / Z_o.

How can I do that? I have no idea as I am a FIDAP newbie, Thanks Ludwig
