Aeration Tank Simulation

Puni1993 · August 29, 2017, 05:44

Im running the simulation using cfx to find the pressure of the air and water acting on the bio-media inside the aeration tank. The bio-media is fully submerged into water where there is no water inlet or outlet. Air entered the reactor at the speed of 1 m/s from bottom to top. There is negative pressure acting on the bio-media. According to my supervisor, there should not be any negative pressure. I tried so many changes to the setup but still having the same problem. Im hope someone can help me Thank you in advance.

why don't start with posting screenshots of your setup, your mesh and attach your *.ccl file? Your chances for an answer and help will be much higher that way.

Hi Maxim. Im sorry. Im new to CFX. Where can I get the .ccl file? I have attached the image of geometry and mesh. Thank you.
