does this simulation make any sense ??

becuase as u can see the velocity should decrease when the pressure increase and the vise versa ?? plz suggest

thanx

i do not really understand your system, ist there a fan in the box? I assume an airflow direction from the left to the right. A Fan should increase the total pressure. After passing the fan there is a kind of diffusor, here the dynamic pressure decreases and the static pressure increases. This leads to less velocity after your "box". I see a lot of swirl after your box, so there is still room too improve the system. Dynamic enery after the system is a loss.
