I am trying to simulate a conjugate heat transfer simulation between two fluid domains, separated by solid domains. I have attached a view of the domain (where S represents solid and F represents fluid).
I would like to have periodic boundary conditions in the streamwise and transverse directions (similar to DNS). The problem is that I am not able to define periodic conditions in the fluid domain with different mass flow rates and temperatures. I am able to define only one set of periodic conditions which are applied to both the fluid regions (one mass flow rate and temperature). I would also like to add that the two-fluid domains are not connected to each other.
I would like to know if it is possible to define two sets of periodic conditions through UDF or through options in fluent.
