    Closed loop simulation

    Stepan Lasak

      Hello folks!

      I need your help with my setup:

      - closed loop which consist of diaphragm gas pump and two boxes (box1 - air tank, box2 - air treatment), the gas is air at atmospheric pressure

      FL-SIM.jpg

      How it works?

      The air is sucked from box1 and is treated in some way at box2 and then goes back to box1. I know the volume flow of pump at atmospheric pressure.

       

      What I need?

      I need to simulate the air exchange in box1 (for some reasons I need 90% of air to be treated), so I will know how and where to place holes, atc.. for best exchange efficiency.

       

      Thanks for your ideas and time!

       

      EDIT 8.11: So here is the partial solution with your help (to confirm my understanding and also to help others)

       

      FL-SIM2.jpg

      - the cylinder with holes represents BOX1

      In wizard was selected:

           - two gases - air, and air-treated (copy of air but only another name)

           - time dependent analysis

       

      The initial conditions are:

           - intlet volume flow of air-treated

           - environment pressure of air

           - and volume concentration of air in cylinder 100%

       

      Set time of simulation 0,5s and the picture is the result (cut plot). So far, so good. Will continue with internal fan hint. Big thanks!
