hello thank you in advance anyone who can help me in this problem that is going bugging me.
I am studying a particular type of valve (Tesla's Valve) has conducted a very simple I want to know the pressure difference between inlet and outlet, before sliding the fluid in one direction and then in the other (I use 2 configurations), the fluid is water and there are no particular boundary conditions.
The problem is that when I study in 2D Computational Domain, the values are similar to those of a scientific comparison but when I use 3D computational domain (that of my greatest interest), the values of pressure decrease dramatically.
I don't understand why this difference of values should be similar, I do not know what to do to find the cause.
If someone would be so kind as to help me I would be very grateful, I could provide more specific details.
