Hi, I want to simulate interaction Moist Air with the stationary porous zone.

Moist air has its own concentration (Variable RH)

Packed bed has its own concentration (Variable REACT).


As the air flows through packed bed, decreases its RH. In a meanwhile packed bed increase its REACT and generates heat.

I need your help with approach how it can be done:

I thought about UDF with User scalars, where scalars RH and REACT are stored in moving air and stationary bed respectively.


Maybe it should be done with multiphase model?



If the approach with UDF and UDS/UDM would be possible, then how to write udf and get those custom scalar variables in UDF and change values?

Thank you for you time!

Rafa
