The plenum hvac box is usually equipped around the heat exchangers or fan while it is directly connected to the ductwork on the hvac system. A return plenum takes in that used air and, using the ductwork, sends it back to the core hvac system. The objectives of the simulations are to examine the pressure drop between inlet (windshield base).
