Hello,
I got your point. By "inlet" and "outlet", I meant the passage for the air flow in and out of the heat absorber. If the hot air comes out through bottom, then, there should be cold air entering the heat absorber to maintain the continuity, right? Could you share the velocity contours and vectors?
I suppose you have also applied gravity acceleration upwards and not downwards i.e +9.81 m/s^2 instead of -9.81 m/s^2 (as hot air flows out through bottom).
