Theory for the Interior Fan Boundary Condition
When the Reacting Flow multiphysics coupling feature is active, the mass fraction fields that are discontinuous over the fan. For each species,
ω
i
, an outlet mass fraction condition is applied:
•
If direction is Along normal vector, the outlet mass fraction
ω
i
, avg
is defined by:
•
If the direction is opposite to normal vector, the outlet temperature
T
avg
is defined by:
This means that there is no diffusion over the interior fan, and no migration either.
