Dear all ,

now i am trying to simulate vaccum steam ejector but during simulation i get reversed flow in the suction inlet of the ejector ,how could i solve this problem

i used density base solver and define inlet and outlet as pressure inlet and outlet

Hello,
Please check the values at the boundaries again.

i check the values but in normal operation of steam ejector the discharge pressure is higher than suction pressure does it may be the reason why the simulation dosen't work correctly

How did you initialise the solution? You may need to set a sensible flow velocity to get the ejector flow established. I've modelled jet pumps and getting the core flow right can require a bit more thought than just using "from inlet" or hybrid.
