Modeling Moisture Transfer through membranes – Guidance required

      Hi Everyone,

      I am modeling the moisture transfer through the membrane in ANSYS Fluent. I am using Species Transport Model for this and writing the UDF to define the mass fractions at the surface of the membrane. After defining the mass fractions, I need to calculate the mass flux through the membrane. This mass flux is dependent on membrane properties and I have the relationship for the calculation of mass flux.

      But I am confused about the selection of  Define_macro to be used for mass flux in UDF.

      I request the seniors to please guide me in this problem or recommend relevant reading materials. Thank You.
      Best Regards

      Hi,

      I suggest you to check Ansys customization manual: 2.3. Model-Specific DEFINE Macros (ansys.com)

      Thank you.
