    Internal Fan Modeling

    Wayne Peng

      Hi, I am doing an internal flow thermal study. I have a question about creating an internal fan. The way I created the fan is to create a rectangular solid block and split line the circular fan openings on both front and back faces.


      Then I insert internal fan to my flow simulation project. After I selected the circular (split lined faces) outlet and inlet faces, the flow arrows I got are in opposite directions. Are they supposed to point to the same direction to indicate the air flow?? Is this the correct way to create internal fan model?? Or what is the proper way to simulate the internal fan? Any help is much appreciated. Thanks,

          haven't done an internal fan in a long time so i don't remember exactly what happens but i kind of remember them pointing in the direction you expect


          what i'd recommend is starting with just your fan part in an external flow analysis to check that your method is correct. if it still doesn't point the right way in that analysis, post a screenshot of the property manager and what the velocity results look like in a cutplot through the fan
