hi everyone, sorry if my english is not good, I am learning.
I have doubts in this Fluid Dialog Box for a 3D Fan Zone with the value called "pressure jump". I'm simulating a drone and its propellers, the pressure jump (between the entrance and exit of the propeller) obtained by numerical calculations to comply with the simulation is 110 Pascals.
When i put 110 in the dialog box and after of simulation I make that ansys calculate the value of pressure in the propeller i get 40 Pascals.
And when I put 285 Pascals in the "pressure jump" in the dialog box for a 3d fan zone and after of simulation I make that ansys calculate the value of pressure in the propeller again, I get the 110 Pascals that I need.
So i think that i have problems with the concepts, i don't understand very well how does 3d fan zones work. I know that the total pressure jump (static + dynamic) between the entrance and exit of the each propeller is 110 Pascals for the conditions that i am studying. So I don't know why is not the same value, the "pressure jump" in the box dialog and the pressure in the results after simulation.
