Hello NickFL,

Thanks for your reply! Yes it is basically like a recorder. The tip of the tube is sealed but the sides have multiple holes in it. So water is injected into the box at a constant laminar flow rate and the fluid enters the sides of all of the holes and exits the box from the inner tube leading outside the box. When I mean multiple simulations I mean the tubes have different lengths. For example in simulation 1 a box that has 800 mL of fluid had a tube inserted 8 cm into it. Simulation 2 has the same 800 mL of fluid but now the tube is advanced to a depth of 14 cm, and simulation 3 35 cm. I am trying to calculate what is the total resistance that each piple based on the different depths is providing to the system. So is the pipe that is 14 cm vs 35 cm more resistant to flow ? Is the resistance of the total holes ? the drag outside the tube ? which settings do I used in the post solver to help me calculate the resistance as a measure of pressure drop vs flowrate in the holes and the drag from the surface. This is what I am looking to do and not sure how to do that in fluent post results. Thank you so very much!


And yes totally not their year but can't give up on them!
