Reactions in the Transport of Concentrated Species Interface

Please login with a confirmed email address before reporting spam

Hi everybody,

I want to build an axisymmetric 1-D model of an adsorber regarding three species. Therefore, I'm coupling Darcy's Law with the Transport of Concentrated Species.

My problem is, that I can only embed reactions for two species though the third species adsorbs as well. Regarding species 1 and 2 is necessary as these two have to be fully removed from the third one (w_3=0.99 Ma-%). But due to its high mass fraction the variation of the mass flow of the third species must not be neglected as it affects the pressure drop inside the adsorber during the adsorption and the regeneration phase. Do you know, how I can include another reaction term for the third species?

Best regards,
Martin
