Nanofiltration modelling

JanoVR · February 7, 2017, 06:57

I am trying simulate the separation of a catalyst from a post-hydroformylation reaction mixture by means of a nanofiltration membrane.
My aim is to model the catalyst rejection potential of the membrane using CFD. I have some basic knowledge of using CFD by using ANSYS Fluent. I am however not sure how to model or rather define a membrane in Fluent.

I was just wondering if someone might have some advice on how I can go about defining a membrane. My system consists of a inlet chamber (retentate chamber), a membrane, sintered metal plate, and an outlet chamber (for the permeate chamber).

Any advice will be much appreciated.

Hi Jano,

Have you tried modeling the solution diffusion equation at the membrane surface using a User defined function? This could be a start.
