I'm doing simulation of the heat transfer of Fuel Cell, I have an exhaust fan on
the outlet and the inlet is the hole between the stacks, due to the thousand
hole of it, i would like to draw a air hood for the inlet,but now i'm facing a
problem which is how to set the hood wall to free stream boundary condition, so
that it doesn't affect the result, since the real fuel cell does not have the hood for it.
TQ.
