Flow simulation : Need help about a fan

Mael Wongso Feb 10, 2018 5:14 PM

Hello my name is Mael and i need to use flow simulation for a Highschool project which contributes to my degree. So I have a problem with Flow simulation, Indeed, I created a fan and I would like to simulate the flow of the Air coming through the fan. Now, whenever I increase the speed of the rotating region, the flow of the Air doesn't change at all. That doesn't seem correct to me, If someone could help me please. Thank you for your answer, have a nice day.

Hi Mael,
The pictures themselves are probably not enough to help you on this. Can you attach the model that you are running this flow analysis on so we can all take a look through it directly?

  Hello Ryan,
  Here is the model i work on. It's a model I took on GrabCad. The file doesn't contain the flow analysis because the complete file is on the school server and I am using my personal computer which doesn't have SolidWork. Thank you, waiting to read you as soon as possible.

    Mael,
    Having the models is a good start. We will need your own files that include the flow project in order to figure out why your setup is not working as expected though. Grab those from your school when you can and put them up here.

      Hello Ryan,
      I am sorry to answer you this late but i didn't have access to school computers last week. So here I added the model i am working on.
      Thank you. pc fan.7z - Google Drive

        Mael,
        Looking at the model and now looking back at the pictures you supplied, the only thing I see in the setup right now that may be an issue is that the computational domain is very small as compared to the fan model itself. Have you tested the analysis with larger computational domains?

        Hello Ryan,
        I thank you a lot for helping me but if i change the computational domain there is any difference. And i dont understand why i can't choose the fan directly as the rotating region. Thank you !
